Question

Why do you fall in the forward
direction when a moving bus
brakes to a stop and fall
backwards when it accelerates
from rest?
​

Answer 1

Answer:

When a moving bus brakes to a stop, our feet come to rest with the bus. But upper part of our body continues to move forward on account of inertia of motion. That is why we tend to fall in the forward direction.

However, when the bus accelerates from rest, lower part of our body moves with the bus. The upper part of the body tries to maintain itself at rest on account of inertia of rest. Therefore, we tend to fall backwards.

Answer 2

Answer:

In a moving bus, a passenger moves with the bus due to inertia of motion.

Explanation:

As the driver applies brakes, the bus comes to rest. But, the passenger tries to maintain the inertia of motion. As a result, a forward force is exerted on him. Similarly, the passenger tends to fall back when the bus accelerates from rest because when the bus accelerates, the inertia of the rest of the passenger tends to oppose the forward motion of the bus. Hence, the passenger tends to fall back when the bus accelerates forward.
