Question

State the law of inertia . Why do we fall in forward direction when moving bus stop suddenly and fall in the backward direction if it accelerates from rest

Answer 1

If an object is said to be on rest it tends to be at rest; if it is moving it tends to be moving. This property of an object is called Inertia.

Answer 2

LAW OF INERTIA

it states tat an object is said to be at rest or at uniform velocity untill and unless an external force is acting on it.

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.

Similarly, when a bus is accelerated from rest, the tendency to be in rest, a person in the bus falls backwards.
