Question: Why is it more difficult to start pushing a heavy object than to keep it moving?
Answer options:
- Kinetic friction is greater than static friction. ✅ Static friction is greater than kinetic friction.
- Gravity's effect is stronger at rest.
- The object gains momentum as it moves.
Correct answer: Static friction is greater than kinetic friction.
Explanation: Static friction (friction when an object is at rest) is generally greater than kinetic friction (friction when an object is in motion), requiring more force to initiate movement.
