1. Friction Lab Activity 11/1/11, 11/2/11 & 11/3/11
2. Objective: To determine the factors that affect friction.
3. Pre Lab: 1. In what ways do you think surface area of an object will be affected by friction? (The difference of a block sliding flat compared to a block sliding on its edge.)
2. Draw a free body diagram of a block being pulled to the right across a horizontal surface. In relation to the direction of motion, which direction does the force of friction act?
3. Predicted the order from least force needed to greatest force needed to slide the block across the surfaces of the bock and: (- metal ramp, - carpet, - lab bench, - cardboard)
4. What effect do you think mass has to do with friction? (If you add more mass what will happen to the force of friction?)
