I'm taking physics lab course. this lab was on "kinetic friction". the questions says to describe how you can measure the kinetic friction force from acceleration acquired through computer based data collection program. Here's the lab and questions that i need to answerC. Kinetic Friction:Now we want to measure the force of friction on a moving block and find how it varies as we change conditions. Use the position sensor to measure position, velocity and acceleration of the block. Go to page 2 of the logger pro program, connect the position sensor to “Dig sonic 2 input” and disconnect the force sensor. Give the block (on the track) a sharp push towards the position sensor, let go and let it slide to a stop. Measure the position vs. time using the position sensor. From the LoggerPro data you should be able to measure the acceleration of the block after you let go. Describe how you can measure the kinetic friction force from this. Make detailed notes about your observations on each of the following:C1. Is the kinetic friction force a measurable quantity? C2. Does it depend on area? C3. Does it depend on normal force? C4. Does it depend on speed? C5. Does it depend on position along the track?C6. From your measurements can you make a simple model? Over what range of values have you been able to test your model? Again, as for static friction, is your model consistent with the text book? I just don't know how to explain "why" for each...
