List the requred material of perform an activity to demonstrate the force of friction and write the procedure
Answers
Answer:What materials cause friction?
Friction is the resisting force between two objects sliding against each other. When we rub our hands together on a cold day it is friction that produces the heat. What happens when you try to walk on ice? You can walk slower to maintain balance or slip. This occurs because there is little friction between the sole of your shoe and the ice. Friction is a necessary force in our world. Without it we would not be able to walk or hold objects in our hands. In this experiment we will examine the nature of friction and how various materials affect movement.
