Forces and Friction: PhET Lab Introduction: Friction is defined as the resistance that one surface or object encounters when moving over another. This would mean that the net force would be in the direction of the frictional force and the block would accelerate that way. The coefficient is assigned to a pair of materials not just one material. During the experiment it is found the most of results are found inaccurate.This is know . The rougher the surface the more friction is produced, this is why rockets are streamlined! Objective. Theres a lot more friction with the velcro as its surface is much rougher. 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. Since the elastic strings actually have mass. Show your work. The block and the plank slide horizontally. If gravity is very strong it becomes harder to slide a body on a surface because of increased force of friction. Its much easier to skid on a smooth surface like wood than a rough surface like carpet, this is because of friction. Note the increase in the spring balances reading which indicates the static friction . Experimental value of is much smaller than . Classroom experiments measuring the coefficient of kinetic friction usually utilize the same setups as for measuring s ; one determines the force necessary to maintain a constant speed using a . This is because there is more friction between the car and carpet than between the car and smooth surface. Also, experimental value of is much smaller than . Step 2. N is the normal force, sometimes it's denoted by . Every time we added more normal force upon the brick, we found out that the frictional force also increases. Use the kinetic friction force and your known normal force from above to calculate a kinetic friction coefficient. 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. 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. Required fields are marked *. Here is an example of uncertainty. Learn how to set up your own friction experiment with Ms. Force Lab Report Conclusion associate that we have the funds for here and check out the link. Part Two: Force vs. 17 Limiting static friction is greater than kinetic friction. 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.

Forces can make object moves or stop, speed them up or slow them down. The underlying purpose of this lab to was to determine the relationship that existed If you push a toy car it moves, if you push it harder it moves faster. 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. Once the body starts to move over the rough surface, the friction would decrease slightly to a value known as kinetic friction . I will be definitely be featuring these ideas on my latest post (www.thegrade3teacher.com). Both scenarios are bad when manufacturing plastic bags for mulch. It increases with . Now I get to do something with that force scale I built. We put 1,000 grams on top of the brick for each trial. A unit-less ration between normal and frictional force that differs among B. Coefficients of friction for various materials 4. Again, the model says it doesn't - still a good thing to look at. Typically the smoother the surface is the less friction. Use the following lab report to record your hypothesis, materials, procedures, observations, and conclusion. Weve got friction experiments, gravity experiments, air resistance experiments and lots more! All rights reserved. Try pushing the car and comparing with the distance travelled if there is no extra force. As for directions, the frictional force is parallel to the surface of the two objects interacting. Also written as . model and understanding slope and y-intercept, we were able to identify the general formula 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. perpendicular to the surface. Its all about the forces. the coefficient of friction. The There are many examples of where friction is a useful 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. Once an object is moving, the magnitude of kinetic friction fk is given by. 2, greater than 1. you 0000011324 00000 n For example, friction is why we do not slip when we . Great input. The normal force of the brick was 1,510 grams and frictional force was 15.6 Newtons. This ratio is specialized to two objects interacting, creating Your hands probably got warmer, right? Random and Systematic Errors Systematic errors include measuring mass of blocks (due to inaccuracy of the electronic balance) and the force (due to inaccuracy of the spring balance). The coefficients will never be bigger than 1 and the coefficient Another way to investigate friction is to make a homemade friction ramp. maximum force which can be used to calculate s. See fig 6-2 and theory section. This explanation from the Khan Academy is terrific so I will borrow it: "The force of static friction is a force between two surfaces that prevents those surfaces from sliding or slipping across each other. 0000013633 00000 n : an American History, cash and casssssssssssssshhhhhhhhhhhhhhhhh, ATI Palliative Hospice Care Activity Gero Sim Lab 2 (CH), Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1.

So, if I pull on the block with 8 LDU the block does not move. Learn about reducing friction with this easy Hovercraft. What is the rise on the celsius scale ? I had a request some time ago to talk about friction. . Keep pushing the wooden plank to maintain a steady sliding, and note again the spring balances reading which now indicates the kinetic friction . 0000009856 00000 n Last Updated on May 4, 2021 by Emma Vanstone. If you want to know what the cloud of gas that surrounds the planet is really doing for us, you have to see what the world would be like without it. 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. It is not until around 10 LDU that it moves and then the scale drops to a much lower value. It is the essential source of information and ideas that make sense of a world in constant transformation. 3. The normal force is the force exerted between the two surfaces (which doesn't have to be the weight - just a warning). We dragged the brick up a wooden board. The math model tells us a couple of things. : an American History, cash and casssssssssssssshhhhhhhhhhhhhhhhh, ATI Palliative Hospice Care Activity Gero Sim Lab 2 (CH), Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1. Friction, simply described for students in elementary school is any force that slows or stops motion. Diffusion models generate incredible images by learning to reverse the process that, among other things, causes ink to spread through water. Can you find some materials that do NOT agree with this model? data collection process because as we increased the normal force on the wooden block, the 0N as well, as the materials are not interacting against each other which leads to no friction. A film canister rocket is a great demonstration of lots of different forces, but it falls back to the ground thanks to gravity. If we only used 1 spring scale, the arrow will go off the measurements, so we had to use 3. k values obtained from the rst experiment by making use of the force sensor. Discussion Assumptions 1.
