Why do we wear shoes with grooves on the soles?
- A. To increase friction
- B. To decrease gravity
- C. To make the shoe heavier
- D. To reduce air pressure
Answer: A. To increase friction

A box is pushed with a force, but it does not move. Which is the best explanation?
- A. No force is acting on the box
- B. The applied force may be balanced by friction
- C. The box has no mass
- D. Gravity is absent
Answer: B. The applied force may be balanced by friction
If the box does not move, the applied force may be balanced by static friction. Balanced forces result in no change in motion.
