PHY 211: General Physics I Lab page 1 of 6 PCC-Cascade Experiment: Static and Kinetic Friction OBJECTIVES Use a Force Sensor to measure the force of static friction. All of the force is not pulling against friction, just the x-component of the pulling force. Rub the lucite rod vigorously with the silk cloth. The surface in contact produces frictional force. Friction is not itself a fundamental force. It is a force that opposes motion or makes it hard for an object to move across a surface. It's represented by the equation; N = m x g. If the object or plane is inclined at an angle (), the normal . 8. The formula for the coefficient of kinetic friction is given by; k = Fk/N. endobj 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]. Copyright 2022 Science Sparks - Wild Sparks Enterprises Ltd, Ideas For Learning About Forces and Motion. The adult involved is fully responsible for ensuring that the activities are carried out safely. the surface was not moving the block in a constant velocity. This was throughout our Add more road surfaces to your DIY friction ramp. Replace the wooden plate with the plastic plate and brick respectively. The rougher the surface the more friction is created. Friction, simply described for students in elementary school is any force that slows or stops motion. Make a bottle rocket, remember you need lots of space for this one. 0000006666 00000 n To read the essays introduction, body and conclusion, scroll down. 0000036774 00000 n Also, coefficients of static and kinetic friction can be compared.

Where, F k is the force of kinetic friction. So the difference of magnitude between these two types of friction is very significant for a human. When we lift the pencil the whole bottle will be lifted. Finally, do you know why a balloon makes a funny noise when you let it go? Perhaps a better thing to do would be to pull the block at different angles and plot Fp vs.theta. By participating in this experiment, you can easily conclude that textbooks do not normally move by themselves, they have to be moved by a force. The math model tells us a couple of things. Be prepared to start your timer. You should find it's easier to slide with socks as there's less friction. The math model for this experiment is Force of Friction = .54 * Force Normal - 1. Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill. If we only used 1 spring scale, the arrow will go off the measurements, so we had to use 3. Try pushing the car and comparing with the distance travelled if there is no extra force. Most land vehicles rely on friction for acceleration, deceleration and changing direction. A unit-less ration between normal and frictional force that differs among objects. When a body is in contact with a rough surface, friction arises at the contact surface if the body is subjected to an applied force. Where: Fs = force of static friction in newtons (N) s = coefficient of static friction (no units) FN = normal force between the surfaces in newtons (N) Maximum static friction is achieved when the inequality becomes an equality, at which point a different force of friction takes over as the object begins to move. Collect three of your school textbooks that are different size and weight (you can use books of various sizes that you have at home as well). Our cars travelled a shorter distance when we used the carpet surface than when we used the smooth surface. Also, we can ensure the applied force is horizontal by fixing the spring balance on a horizontal platform. motion or attempted motion of one surface across another surface. This is just a ramp with different surfaces. Weve got friction experiments, gravity experiments, air resistance experiments and lots more! Essay, 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. 0000003487 00000 n Friction is a force which opposes the sliding motion of one object over the surface of another object. I thought I did. between the force of friction and the normal force of a slide block. the table is .54. Another way to investigate friction is to make a homemade friction ramp. The use of oil in a cart engine, the use of right lubrication in skating as well as in basketball, the screeching sound of a sudden . We depend on friction to keep our feet from sliding out from under us and to keep us safe. Friction is surprisingly complicated. 0000012055 00000 n 0000001842 00000 n 16 It make sure the blocks are experiencing constant applied force. The basic answer is that the stuff the two surfaces are made of (atoms) are interacting with each other. This maximum value is the limiting static friction. Have you ever tried to slide on a gym floor wearing sneakers and then wearing leather-soled shoes? Take rice about 1 kg. Calculate first, then test each object in the table below with the simulation on a horizontal plane. We also experience both of them in the experiment. 3 Conclusion In the Inclined Plane Friction Lab the relationship between normal.

This result tell us both limiting static friction and kinetic friction are directly proportional to the reaction force. Great input. The normal force of the brick was 1,510 grams and frictional force was 15.6 Newtons. In this case, the mass remains at 0.25 grams which means that no weight was removed. 2. The complexity of these interactions makes the calculation of friction from first principles impractical and necessitates the use of empirical methods for analysis and the development of theory. Q. 18 In the design of the braking system in bicycles, what parameter(s) should be maximized to achieve a larger frictional force? Its much easier to skid on a smooth surface like wood than a rough surface like carpet, this is because of friction. Note the readings. Also written as . Record the time and distance that each book traveled on the three different surfaces on your provided 49ers Frictional Force worksheet. In our static and kinetic friction lab, we were able to see how the weight of an object affects its friction, measure its coefficients, and decipher is the weight affects the coefficient. , the 240 V mains supply? Once the body starts to move over the rough surface, the friction would decrease slightly to a value known as kinetic friction . The net force in the y-direction (vertical) is zero. Direct link to Sung Woo Hong's post What is a 49er and what t, Posted 4 years ago. 0000036797 00000 n maximum force which can be used to calculate s. See fig 6-2 and theory section.

Note the angle and find the coefficient of friction. 0000008936 00000 n This ratio is specialized to two objects interacting, creating What will happen if he connects 100 LEDs, all in a parallel combination, to 0000003305 00000 n Does the coefficient of friction (both kinetic and static) depend on the surface area? Calculate the force of friction using the formula: F = n. you Measure and record how far it travels. remains constant even the applied force is increased further. It is an important concept in a variety of fields, including engineering, physics, and materials science. Slowly push the wooden plank (together with the trolley underneath) away from the spring balance. Find out why you slip and slide more on smooth surfaces than rougher surfaces with this slipping and sliding activity. The frictional force increased to 40.0 Newtons, a difference of 24.4 Newtons compared to the very first trial that we did. Friction Force Lab Conclusion After analysis of the data, we found that our hypothesis is true in which the static and kinetic friction is affected by the mass of the object. stream It remained stationary relative to the wooden plank. When the applied force exceeds the limiting static friction , the body will start to slip over the rough surface. A force is a push or a pull. It was really easy to contact her and respond very fast as well. I love these ideas, they are fantastic!! Force Lab Report Conclusion associate that we have the funds for here and check out the link. 3. That is, f s (max) = s N. Static friction is a responsive force that increases to be equal and opposite to whatever force is exerted, up to its maximum limit. between the two objects (surfaces) interacting, you will be able to find the force of friction on Does the extra force make a difference? The reason it slows down is because of two forces, air resistance and friction. 0000001300 00000 n 1 0 obj This means that the net force must be zero. Factors contributing to friction include the coefficient of friction () and the normal force. A lighter object needs less force to move than a heavier object. There are many examples of where friction is a useful force. Some forces are in direct contact with objects, while other forces are not. The kinetic friction force F k exhibits a similar dependence on normal load as the static friction force F s does, except that F k is a little bit smaller than F s under the same pressure. To estimate and compare the coefficients of static and kinetic friction of different materials. The ratio is noted as 31 1 CONCLUSION It is generally recognized that control of friction processes is extremely diffcult, or even impossiblebecause of the complexity and diversity of phenomena occurring on a standard dynamic contact. Dry friction arises from a combination of inter-surface adhesion, surface roughness, surface deformation, and surface contamination. In this lab, my partners and I tried to find out what the relationship between the normal force and frictional force of a brick is. %PDF-1.5 Measure the coefficients of static and kinetic friction for a particular block and track. Design and build straw rockets and launch at different angles to investigate how the flight trajectory changes. 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. The goals of this lab experiment are to record the kinetic and static frictional forces by the use of a force sensor. Notice that there is a different coefficient for static and kinetic (sliding) friction. Create an applied force and see how it makes objects move. In our experiment we figured out the value of the coefficient of static friction to be 0.52229 and the value of the coefficient of kinectic friction to be 0.45797 and 0.60758. By common sense, brick is the roughest and plastic is the smoothest. 81 m/s2 (recall Fw = mg). Use the same face of the wooden block. Therefore the pull force you measured with the force probe must have been equal to the kinetic frictional force. In this activity you will examine how static and kinetic frictional forces vary as the normal force between an object and a surface is changed. Again, the model says it doesn't - still a good thing to look at. Conclusion: In the Inclined Plane Friction Lab, the relationship between normal force and frictional force betweenwood and steel was determined, as well as how to use a surface at multiple angles and the force needed to move an object on that surface to determine a the frictional coefficient between two objects.
