Answer 1

Answer:

A, B, C, D

Explanation:

A. The friction between the floor and the banana peel is very less that is why we slip

B. Lighter box has less resultant force and less friction unfortunately it is opposite for heavy box

C. When object is at rest we need greater force to move becoz of gravitational energy but when it is in uniform speed gravitational energy is less and less force is needed to move

D. They use spike shoes for lesser friction so that they can move easily and to stop immediately by : less area, more pressure.
