Why do you fall in the forward direction when a moving bus brakes to a stop and fall backwards when it accelerates from rest?
As we know by newton first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force
(a) In a moving bus, passengers are in motion along with bus. When brakes are applied to stop a moving bus, bus comes in the position of rest. But because of tendency to be in the motion a person falls in forward direction.
(b) Similarly, when a bus accelerates from rest, we tend to fall backwards because when a bus is accelerated from rest, the tendency to be in rest, a person in the bus falls backwards.
