  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:

                  In a running bus, our speed is equal to the speed of bus. As a moving bus brakes to a stop, the lower part of our body being in contact with the bus comes to rest, but the upper part due to inertia of motion, remains in the state of motion. Hence, we fall in the forward direction. When the bus accelerates from rest, the feet come into motion while upper part of the body remains at rest due to inertia of rest; hence, we fall backwards.
