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?
Solution
When a moving bus brakes to a stop, the lower part of our body which is in contact with the bus comes to rest while the upper part of our body tends to keep moving due to inertia of motion. Hence, one tends to fall forward. When the bus accelerates from rest, the lower part of our body comes into motion alongwith the bus while the upper part of body tends to remain at rest due to inertia of rest. Therefore, we fall backwards.
