Question

(a.) Why do you fall in the backward direction when a bus accelerates from rest?
(b.) Name the physical quantity that measures inertia. State its S.I. unit

Answer 1

Answer:

a) Inertia in a moving bus when brake is applied

Inertia in a moving bus when brake is appliedSimilarly, 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.

b) Mass.
