A man leaves his house for a cycle ride. He come back to his house after half an hour after covering a distance of one km. What is his average velocity for the ride?
Correct answer: B. 0
- A. 2 km per hour
- B. 0
- C. 1/2 km per hour
- D. 1/2 km per second
Explanation
Average velocity is total displacement over total time; since he returns to the starting point the net displacement is zero, so average velocity is 0 regardless of distance traveled.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
