NAME: _________________ LAB WORKSHEET: CHAPTERS 5-6 PERIOD: _____ 1) The purpose of the lab is to determine the effect (if any) of contact area on the magnitude of the kinetic friction force acting on a wooden block. The block will be accelerated on the tabletop by a modified Atwood’s machine apparatus. The first set of trials will be performed with the block sliding on its base, and the second set will be performed with the block sliding on its side. You will record the acceleration of each trial with a vertically mounted photogate. a) What do you predict will be the effect of increasing the area of contact between the block and the surface of the table? Be specific. b) Assuming your prediction is correct, describe the data you will collect. Be specific. 2) Perform the trials as directed by your teacher. Fill in the table below. Block on base (large contact area) Block on side (small contact area ) Trial # Acceleration (m/s 2 ) Trial # Acceleration (m/s 2 ) 1 1 2 2 3 3 4 4
