Question

Describe two examples of activities that you do where you depend on friction, and would not be able to do them without friction.

Answer 1

Answer: One is when a bike stops. The other is when you rub your hands together to get warm.

Explanation: Force and friction affect our daily lives in numerous amounts of ways. For instance, when a football is kicked, it moves faster later after some time its force decreases due to friction. A common example of friciton is when a bike stops. When the brakes are applied the friction on the pads cause the bike to stop. The other is because you are getting warm with friction.
