Question

1. explain the difference between static and kinetic friction, providing a real - world example for each to illustrate how they affect motion.

Explanation:

Static friction acts on stationary objects to resist the start of motion. For example, a heavy box on the floor doesn't move until enough force overcomes static friction. Kinetic friction acts on moving objects and opposes their motion. Like when a sled is sliding on snow, kinetic friction slows it down.

Answer:

Static friction resists the start of motion (e.g., heavy box on floor). Kinetic friction opposes ongoing motion (e.g., sliding sled on snow).
