Conclusion. 8. The data showed that the two forces are directly related. frictional force increased proportionally. Find out how you can stand on a paper cup without it breaking. The experimental results prove our assertion. 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. 103 0 obj << /Linearized 1 /O 105 /H [ 1300 542 ] /L 982964 /E 62027 /N 10 /T 980785 >> endobj xref 103 44 0000000016 00000 n Friction is opposite to the direction of push applied on the body to make it move. The friction process itself is a superposition of multiple interactions, which leads to the complexity of research in friction mechanism. Note the increase in the spring balances reading which indicates the static friction . Kinetic energy is converted to thermal energy whenever motion with friction occurs, for example when a viscous fluid is stirred. Forces can make object moves or stop, speed them up or slow them down. Theres a lot more friction with the velcro as its surface is much rougher. Force of Friction = .41 * Force Normal + 1. 0000006688 00000 n >> Complexity level: 6. 0000007871 00000 n The adult involved is fully responsible for ensuring that the activities are carried out safely. The math model for this experiment is Force of Friction = .54 * Force Normal - 1. Keep pushing the wooden plank to maintain a steady sliding, and note again the spring balances reading which now indicates the kinetic friction . What Would Earths Temperature Be Like Without an Atmosphere? In both of these cases, the block does not move (doesn't not accelerate). Most land vehicles rely on friction for acceleration, deceleration and changing direction. Friction is not itself a fundamental force. Thanks for these ideas It will help my kids learn about forces. When pulling the plank, the spring balances reading represents the frictional force. Kinetic Friction is also known as sliding friction, and is the amount Watch what happens. Tie strands of string around each textbook, and this time, pull each book and record the time it takes to pull the same distance you pushed the book on the three surfaces. In football we often want to maintain contact with a surface to utilize good friction to our advantage, but at the same time, we might not want materials heating up or slipping, so players desire to minimize poor friction. Theory. Which surface allows a car to travel the fastest? Have you ever hurt your knee when sliding on carpet? Also written as . If I pull with 9 LDU, it still doesn't move. The math model for this experiment is Force of Friction = .54 * Force Normal - 1. Slightly more simple and much more powerful is our balloon powered car. 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. The video above is not a very good example because the block is not being pulled at a constant speed. The block and the plank slide horizontally. The nano-friction behavior of nickel-based Ag film composites was evaluated using molecular dynamics simulations.

The value of the. Force 1 I know I said it was complicated and that doesn't seem to complicated - does it? Let me write the force equilibrium equations for the x- and y-directions: I guess I never said it, but theta is the angle the force is pulling measured from the horizontal. Record the findings in tables similar to Data Table 3. An example of a possible error could be that the person pulling the block across More and more ways have been developed to study the physical and chemical process involved in friction. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Get new experiments straight into your inbox every week!! Have you ever tried to slide on a gym floor wearing sneakers and then wearing leather-soled shoes? When two surfaces rub against each other, why is there a friction force? Students looking for free, top-notch essay and term paper samples on various topics. Typically the smoother the surface is the less friction. Here I have a block on a table. The simple pendulum - Lab. Therefore the pull force you measured with the force probe must have been equal to the kinetic frictional force. The math model tells us a couple of . Air resistance is air pushing on a moving object which slows it down. Use a little whipping motion at the end of the rubbing. The ticker tape can be split into sections once the experiment is done and it should display a gradual increase in speed over time, that is until the surfaces with a higher coefficient are added to the experiment. The fourth such activities are all factors that affect the small force great friction. The force table allows you to. Since the normal force is smaller, the frictional force will be smaller. 4 0 obj << Pop the lid off a bottle with these coin poppers. In recent decades, the calculations, analyses, and experiments in tribology have all improved a lot. 6. 18 The reaction force exerted on the braking pads and the coefficient of kinetic friction should be maximized. (b) Use blocks with greater mass (e. g.lead blocks). We found these numbers out by using the spring scale. 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 next part of the lab holds the mass constant and experiments with how acceleration changes if different amounts of power are exerted onto the weight. Learn how to set up your own friction experiment with Ms. Forces can make object moves or stop, speed them up or slow them down. The goals of this lab experiment are to record the kinetic and static frictional forces by the use of a force sensor. Especially for a car with mass generally over 1000 kg, the reaction force is very large. A film canister rocket is a great demonstration of lots of different forces, but it falls back to the ground thanks to gravity. Compare how things move on different surfaces, Last Updated on May 4, 2021 by Emma Vanstone. The objective of this article is show an easy way to measuring both dynamic and static friction factor between two solid surfaces, using Tilted plane method. Experimental value of is much smaller than . Here's how: Put the lid on the bottle and tap the bottom of the bottle on a hard surface. Limiting static friction Friction always opposes motion. For example you could push an empty box easily, but a filled box would be harder, it would need more force to move. I think you can still see that the frictional force to pull it sliding is less than for it stationary. To find out the relationship connecting normal force and frictional force acting on an object; take measurements of the coefficients of kinetic and static friction between surfaces to verify that these two figures are autonomous . 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. Create an applied force and see how it makes objects move. On our final trial, we increased the normal force of the brick to 6,510 grams. 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. Aluminium, Brass, Nylon, Steel. : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Force of Friction (2008/12/17) 1. Figure 6 . Try pushing the car and comparing with the distance travelled if there is no extra force. The math model will be. 0000038220 00000 n Explore gravity and air resistance with these simple paper spinners. Every time we added more normal force upon the brick, we found out that the frictional force also increases. Try this easy inertia experiment where an object drops straight down into a glass! Add 1 more block (totally 3 blocks). Forces can also make objects change direction or shape. The two other types of friction are rolling friction and fluid friction. Use the following lab report to record your hypothesis, materials, procedures, observations, and conclusion. Also, coefficients of static and kinetic friction can be compared. But when we slid the block on the cloth, we got a different ratio. Find out why you slip and slide more on smooth surfaces than rougher surfaces with this slipping and sliding activity. Therefore, making the data Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites. Once you've added a bit more rice, stick the chopstick back into the bottle. For these, you will be comparing experimental values (say coefficients for different areas). Discover why we salt/grit icy roads in winter. 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). This will result in greater fluctuation of frictional force and thus greater experimental error. When we lift the pencil the whole bottle will be lifted. We are investigating the effect of friction on the distance travelled by a car, so the ramp surface is our variable, everything else must be kept constant. Being sure not to damage the textbook, slide the textbook along various surfaces, keeping a keen eye on the frictional force that each surface has on the movement of the textbooks. First of all take a clean plastic bottle or any other strong bottle. As you can see here, the two axes represent force and acceleration (rpm/sec). 0000011552 00000 n Our cars travelled a shorter distance when we used the carpet surface than when we used the smooth surface. What force do you think is pushing against the book as you pulled it? 83% (6) 3. 0000012055 00000 n Friction is a force which opposes the sliding motion of one object over the surface of another object. For this purpose we have found the Normal force and sliding. 0000009856 00000 n Friction is a force that resists a relative motion between two or more objects, like a rubber tire and asphalt have a coefficient . For example, friction is why we do not slip when we . All of the force is not pulling against friction, just the x-component of the pulling force. help. We'll not send WIRED is where tomorrow is realized. frictional force to normal force. Both scenarios are bad when manufacturing plastic bags for mulch. Repeat this experiment for the various carts with 3 di erent masses. Discussion: Static friction is a force found between two surface two surface in a moving object .When an object is moving towards the right the static friction is towards the left which is against the main direction .The coefficient of static friction is . Physics Lab 1 Mass & Density. The underlying purpose of this lab to was to determine the relationship that existed 18 In the design of the braking system in bicycles, what parameter(s) should be maximized to achieve a larger frictional force? We dragged the brick up a wooden board. the table is .54. Problem 4: When we apply brakes in the car, it retards the motion; although it is an internal force. Wow! 0000011324 00000 n The rougher the surface the more friction is produced, this is why rockets are streamlined! Discuss the physical meaning of the spring balances reading in each case. Repeat step 2 to 5. If neither has a tangent plane there, the direction of the normal is indeterminate. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Indeed it would be odd so pull a block to the right and have it accelerate to the left (for a block at rest). To estimate and compare the coefficients of static and kinetic friction of different materials. the surface was not moving the block in a constant velocity. But the plan may threaten the fragile landscapeand a tenacious billionaires ambitions.
