A person is standing on a bus. When the bus starts moving forward suddenly:
Correct answer: D. The person moves backward
- A. The person moves forward
- B. The person remains stationary
- C. The person is unaffected
- D. The person moves backward
Explanation
Due to inertia the upper body tends to remain at rest while the feet accelerate with the bus, making the person appear to move backward relative to the bus. The body's tendency to maintain its initial state causes this apparent backward motion.

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.
