By the end of this lab activity, you will be able to answer the question, \"What is the relationship between the coefficients of static and kinetic friction?" using data to support your answer. For this investigation, you will use the friction mode of the PhET simulation \"Forces and Motion-Basics," which appears below. Using this simulation, you will find the force of friction. Then, you will calculate the coefcients of static and kinetic friction using the formula. Finally, you will determine how the two coefficients compare to each other. Once you have completed the experiment, you will communicate the results by writing a laboratory report. You will create your laboratory report in a word processing program. Make two data tables for recording information. Make one data table for the coefficient of static friction and one for the coefficient of kinetic friction. On each of these data tables, have places to @ record the mass, normal force, friction force, and coefficient of friction for four trials. Compare the coefficient of static friction and the coefficient of kinetic friction and determine how they compare to each other. As you write your lab report, answer the question \"What is the relationship between the coefficients of static and kinetic friction?" Follow these instructions to calculate the coefficient of static friction using the simulation. Coefficient of Static Friction, us The coefficient of static friction is calculated by using the static friction force. This is the force that must be overcome for the crate to begin moving. 1. To determine the static friction force, you will need to add force to the object until the object just starts to move. Use the crate, which has a mass of 50 Kg, and click on the right-facing double arrow twice. This exerts a force of 100 N on the crate. If the crate has not started to move, click on the single arrow until the crate just barely starts to move. If you overshoot the movement, you can reset and start adding forces again. 2. The force at which the object barely starts to move is the static friction force. 3. Record the mass and friction force in your data table. 4. Calculate FR (normal force) for the crate and record it in your data table. 5. Use the normal force and the static friction force to calculate the coefficient of static friction. Follow these instructions to calculate the coefficient of Kinetic friction using the simulation. Coefficient of Kinetic Friction pk The coefficient of kinetic friction is calculated by using the kinetic friction force. This is the force that must be applied for the crate to keep moving at a constant speed once it has started moving. Important Note: To make sure the crate is moving at a constant speed, the sum of the forces must equal zero. 1. To determine the kinetic friction force, you will repeat the procedures for static friction. Once the crate is moving, reduce the force applied using the left arrows until the crate starts moving at a constant speed (no acceleration). Once the crate is moving at a constant speed and the sum of the forces is zero, the friction force shown as the object is moving is the kinetic friction force. 2. Record the mass and friction force in your data table. 3. Calculate Fn (normal force) for the crate and record it in your data table. 4. Use the normal force and the kinetic friction force to calculate the coefficient of kinetic friction. Add another crate on top of the first one. Calculate the new normal force based on the new mass. Record the mass and the normal force of the two crates. Repeat the procedure of pushing on the crates until they just move. Find the static friction force and the sliding friction force and record them in your data table. Use the forces to calculate the coefficient of static and kinetic friction for the two crates. Change the mass two more times by changing the objects. For each mass, record the mass and new normal forces in your data table. Find the friction forces for each and calculate and record the coefficients of static and kinetic friction
