Question

When a fast moving bus is stopped suddenly, the passengers sitting in it tend to fall forwards. This is due to

• A. inertia of rest.
• B. inertia of motion.
• C. inertia of direction.
• D. inertia of speed

Answer 1

The correct option is B

inertia of motion.

Step 1: Inertia of rest, motion

1. The inertia of the rest of a body is a property of a body in which a body wants to always retain its position.
2. The inertia of motion of a body is defined as a property of the body in which the body wants to continue its motion.

Step 2; Explanation for the correct answer

1. When a bus is moving at some speed we can say that the passengers inside the bus are also in motion.
2. when the brakes are applied, the bus stops suddenly the lower body stops with the bus.
3. But the upper body of the passenger is in motion due to which it seems the passengers sitting inside the bus tend to fall forward.

Hence, Correct Answer: Option(B) because of the inertia of motion, the passengers sitting inside the bus tend to move forward when the brakes are applied.
