People sitting in a moving bus experience a jerk when the bus stops. This is due to which of the following?
Correct answer: A. Inertia of motion
- A. Inertia of motion
- B. Inertia of rest
- C. Inertia of acceleration
- D. Inertia of turning
Explanation
Option A is correct since when the bus stops, the people sitting in it experience a jerk. This is because, while the bus was moving, the people were moving with it. Hence, they were having inertia of motion. When the bus stops, the inertia of the bus changes from that of motion to that of rest.

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.
