When a moving bus suddenly applies brakes, the passengers sitting in it fall in the forward direction. This can be explained by

A

the theory of relativity

B

Newton's first law

C

Newton's second law

D

Newton's third law

Text Solution

Verified by Experts

The correct Answer is:
B
This is due to moment of inertia which is explained by Newtons first law of motion. With the application of brakes, the bus slows down but our body tends to continue in the same rate of motion because of its inertia.
