I get: This could be used to solve for the coefficient of friction if you pull at that angle. Types of Forces Lab Report Instructions: In the Types of Forces lab, you will experiment with the contact force friction. Sneakers have enough traction and enough friction to stop you from sliding. Its much easier to skid on a smooth surface like wood than a rough surface like carpet, this is because of friction. Forces can make object moves or stop, speed them up or slow them down. We were able to do all of these things and come up with a solid conclusion in the end. Have you ever tried to slide on a gym floor wearing sneakers and then wearing leather-soled shoes? Force Lab Report Conclusion associate that we have the funds for here and check out the link. : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Here are some other questions that would be great to look at in a lab. Learn about kinetic energy with a homemade slingshot or lollystick catapult. A lighter object needs less force to move than a heavier object. * The coefficient of static friction of brick is 1. You will submit your completed report. Explore energy and bouncy-ness with some balls and different surfaces. Create an applied force and see how it makes objects move. Thanks for sharing! Also written as . Friction is the force between two objects when you rub them together. The block and the plank slide horizontally. 0000004244 00000 n To experience friction firsthand, put your hands together in front of you and rub your palms back and forth. Basically, whenever the normal force of the brick increases, the frictional force also increases. Great input. The basic answer is that the stuff the two surfaces are made of (atoms) are interacting with each other. Repeat step 7 with 3 blocks. Some examples of this formula being used in real would include geese sliding on ice, Science Sparks assume no liability with regard to injuries or damage to property that may occur as a result of using the information and carrying out the practical activities contained in this resource or in any of the suggested further resources. Limiting static friction Friction always opposes motion. f k = k N. lab report friction oluseye dare gamoi paisley objective: to determine the coefficient of static friction and the coefficient of kinetic friction of an object. Also, coefficients of static and kinetic friction can be compared. All of the force is not pulling against friction, just the x-component of the pulling force. As a conclusion to this activity, reflect upon the following questions concerning the magnitude of frictional force applied on the textbooks during testing: When you pulled the textbook towards you, you could feel a force opposing you. All rights reserved. 0000007871 00000 n 3. When we lift the pencil the whole bottle will be lifted. C. Effect of surface area on friction Theoretically, friction is independent of contacting area. So the difference of magnitude between these two types of friction is very significant for a human. Change friction and see how it affects the motion of objects. Discover why we salt/grit icy roads in winter. intercept for this particular part of the experiment was 1. Science is one of those things best-taught hands-on so children can really get a grasp for what they are learning. 59 5. Calculate the force of friction using the formula: F = n. k values obtained from the rst experiment by making use of the force sensor. Sudden reductions in traction can cause loss of control and accidents.

Friction Experiment: Measure Static Sliding Coefficient of Friction with a Ramp. The data showed that the two forces are directly related. Try pushing the car and comparing with the distance travelled if there is no extra force. Kinetic friction coefficients are generally less than static friction coefficients, which is the reason that it is much easier to keep a heavy object in motion than it is to start it in motion [4]. Home Science Experiments for Kids Forces and Motion Ideas For Learning About Forces and Motion. 0000009856 00000 n In procedure 1, it was attempted to find the relationship . the object. The math model for this experiment is Force of Friction = .54 * Force Normal - 1. Once the body starts to move over the rough surface, the friction would decrease slightly to a value known as kinetic friction . g = 9/s 2. Firstly, we place tray at the middle of plane and apply weight on weight hanger until tray starts to move. Another fun activity is to set up a teddy zip line investigation and test different types of harness and materials for the string. 8. 0000036774 00000 n For example, friction is why we do not slip when we . Then the change in force will be used to accelerate to blocks, instead of just balancing the frictional force. I think you can still see that the frictional force to pull it sliding is less than for it stationary. There are many examples of where friction is a useful force. The adult involved is fully responsible for ensuring that the activities are carried out safely. objects. Once an object is moving, the magnitude of kinetic friction fk is given by. An example of poor friction would be when a 49ers player is not wearing cleats and slips and falls when trying to come to an abrupt stop or change directions quickly. contact force friction use the following lab report to record your hypothesis materials procedures observations and conclusion you will submit your completed report name and title name of lab The neoprene gloves that receivers wear provide friction on the football by the receiver gripping the ball with its sticky texture.

You should find it's easier to slide with socks as there's less friction. 0000013633 00000 n If we pull the spring balance directly, the force may not be always horizontal and the useful horizontal component of the force will be smaller than the balances reading. Each LED will have a potential difference of 220 V and therefore they will get damaged. . H|Wn7W8c`(A 9$^ #aX,wcY|tuuueL[22. determined by the amount of mass that is hung from the other end of the string. 2021-22, BI THO LUN LUT LAO NG LN TH NHT 1, Cecilia Guzman - Identifying Nutrients Gizmo Lab, Chapter 2 - Summary Give Me Liberty! The normal force of the brick was 1,510 grams and frictional force was 15.6 Newtons. Since the normal force is smaller, the frictional force will be smaller. In this lab report it was investigated that, the Kinetic and Static friction force between a steel plank and other materials i.e. Air resistance and friction take time to slow an object down, if you want an object to stop quickly you need to apply further force, for example a brake on a bike. As for directions, the frictional force is parallel to the surface of the two objects interacting. Comparison of Experimental with Expected Result A. We were able to see through the use of F=umg, that the weight of the . Discuss the physical meaning of the spring balances reading in each case. Try this easy inertia experiment where an object drops straight down into a glass! In this state of movement, the non-friction force of object . Step 3. Forces affect the motion and speed of a football in the game, and different forces can help or hinder motion in the game at different times. A film canister rocket is a great demonstration of lots of different forces, but it falls back to the ground thanks to gravity. Determine the mean force. If you are ok with a different approach to friction, you can model it quite simply with these two expressions. Make these shooters and explore trajectory and aerodynamics. Record the force, normal force and obtain k graphically. On our final trial, we increased the normal force of the brick to 6,510 grams. The nano-friction behavior of nickel-based Ag film composites was evaluated using molecular dynamics simulations. This was throughout our Can you find some materials that do NOT agree with this model? The effect of mass of strings become practically negligible. Then, by using formula of coefficient of friction we found the value, which was approximately 0.18 at 10, 20 and 30. What if I pull on the block at an angle above the horizontal? << /S /GoTo /D [2 0 R /Fit] >> The measuring process is developed by means of moving plane made of the material we want to study and knew longitude, which can regulate its angle by growing or reducing its height. You will apply a horizontal force to a block of wood loaded with weights in order to pull the block at constant velocity across a horizontal plane. Red Ted Art made a fun elastic powered tugboatwhich moves using the energy stored when you wind up an elastic band. If a car is going at a steady pace uphill, the friction between the tyre of a driving wheel and the road is in the direction of motion, not against it. Friction is a force that is created As you can see here, the two axes represent force and acceleration (rpm/sec). However, the data said . What happens if you double the weight by stacking one book on top of the other? 0000008466 00000 n The Disruptors Who Want to Make Death Greener. It demonstrated that friction is directly proportional to normal reaction but independent of contacting area.

Object Mass Weight Normal Force , Coef of Friction Friction Force to Overcome Dog 0. CONCLUSION: Friction is caused when two surfaces in contact slide over each other. Theoretically, should be only slightly smaller than. Friction. Then connect them to the spring balance and move the trolley until they slide. A force is a push or a pull. investigated the effect of friction coefficient on the thickness model of zirconia ceramic powders by grinding experiments. Also, coefficients of static and kinetic friction can be compared. I will be definitely be featuring these ideas on my latest post (www.thegrade3teacher.com). Use the kinetic friction force and your known normal force from above to calculate a kinetic friction coefficient. We love this idea of investigating with a slide from Buggy and Buddy. Find out how friction impacts Newtons Laws of Motion. by Ron Kurtus (updated 21 November 2022) The goal of this experiment is to measure the static sliding coefficient of friction between two surfaces by using a ramp and measuring its inclination.. All graphs are straight lines passing through the origin. 0000015772 00000 n The coefficient (mu) is just a parameter that is experimentally determined and depends on the two materials interacting. Friction tries to stop objects sliding past each other. These activities are designed to be carried out by children working with a parent, guardian or other appropriate adult. On the third trial, the normal force of the brick was 3,510 grams and the frictional force increased to 33.2 Newtons, a difference of 5.5 Newtons compared to the second trial and a difference of 17.6 Newtons compared to the very first trial that did. Friction is a non-conservative force - work done against friction is path dependent. This sample of an academic paper on Friction Lab Report reveals arguments and important aspects of this topic. Two great concepts to teach your child hands-on are Exploring force and friction. Question: Why does a car roll down some surfaces faster than others? We dragged the brick up a wooden board. This new lab experiment explores the physics involved in our stars tumultuous interior regionsby creating a sphere of plasma. In this lab there is two math models. As for directions, the frictional force is parallel to the surface of the two . Use the following lab report to record your hypothesis, materials, procedures, observations, and conclusion. And this is why the static friction model has a less-than-or-equal sign. Try rubbing your hands together? Each LED will glow but the ones closer in the circuit to the main supply will glow brighter. We found these numbers out by using the spring scale. During the experiment it is found the most of results are found inaccurate.This is know . Acceleration. The relative friction produced by these surfaces can be determined and compared. The coefficient of friction can also be described by dividing Force of Friction by The Normal Force. Y- 0000036797 00000 n This may be due to varying degree of roughness throughout the contacting surface. Make an easy magnet maze with cardboard or even a LEGO maze. Conclusion This experiment was quite successful. (I guess you noticed the protractor I taped on top of the block) Here is a force diagram for that case (assume I am pulling at a constant speed). Equation for Static Friction. The net force in the y-direction (vertical) is zero. Posted 4 years ago. N is the normal force, sometimes it's denoted by . I love these ideas, they are fantastic!! document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Get new experiments straight into your inbox every week!! The math model tells us a couple of things. Does the coefficient of friction (both kinetic and static) depend on the surface area? A tiny Scottish village is betting its future on rocket launches. In this experiment we proved that friction is important in our everyday motion because without it, anybody in motion will not stop because a friction is a force that opposes motion, we defined 2 kinds of friction which is static and kinetic. Every time we added more normal force upon . We found these numbers out by using the spring scale. 4 0 obj << Errors and Accuracy The error of measurement of mass of blocks is . If heavier blocks are used, the difference between and might be smaller. 0000006666 00000 n The math model for this experiment is Force of Friction = .54 * Force Normal - 1.

The coefficients will never be bigger than 1 and the coefficient The WIRED conversation illuminates how technology is changing every aspect of our livesfrom culture to business, science to design. 2. What would happen if the friction force was greater than the force I was pulling? A toy zip line is the garden is a great way to learn about friction and fun science project too! The normal force is equivalent to the weight of the object, so this can also be written as: F = mg. On to the first experiment (using the DIY force scale). The error in taking reading of spring balance is . spam or irrelevant messages, We use cookies to give you the best experience possible. The general idea is that rough surfaces create more friction with the car's wheels, while there is little friction between a car and a smooth surface, causing the car to travel faster and make it harder to stop immediately. This work further improves the flow switching theory and brings a theoretical reference for multi-constrained mechanical systems. To do this, it will be best to report the uncertainties. Complexity level: 6. The player would need some friction to stop, and to also have the ability of their cleats to grasp the fieldturf to slow down their momentum. Friction allows things to start and stop moving and slows them down. The normal force is the force exerted between the two surfaces (which doesn't have to be the weight - just a warning). Effect of applied force on friction Static friction increased with applied force. It is not until around 10 LDU that it moves and then the scale drops to a much lower value. May 4, 2021 By Emma Vanstone Leave a Comment. Q. The video above is not a very good example because the block is not being pulled at a constant speed. The ability for a 49ers player to stop immediately on grass turf with cleats would be an example of good friction. In this lab, students compare the force necessary to move the same object over various surfaces. In recent decades, the calculations, analyses, and experiments in tribology have all improved a lot. How do your values compare with those from experiment 1? We put 1,000 grams on top of the brick for each trial. Figure 6 The testing was done using 3 types of model cars on 5 different types of surfaces. Repeat step 2.
