Question

man getting down from running bus, falls forward because

(a) due to inertia of rest ,road is left behind and man reaches forward

(b)due to inertia of motion upper part of body continues to be in motion in forward direction while feet come to rest as soon as the touch the road

(c)he leans forward as a matter of habit

(d)of the combined effect of all the three factors stated in (a), (b) and (c)​

Answer 1

${\huge{\boxed{\red{\sf{Answer}}}}}$

(b) due to inertia of motion upper part of body continues to be in motion in forward direction while feet come to rest as soon as the touch the road.

Hint : Newton's first Law of motion.

An object remains to be at the state of rest or of uniform motion unless compelled to change that state by an applied unbalanced force.

Inertia of rest and inertia of motion are different.

• The inertia of rest is due to the rest position of the body and,
• Inertia of motion is due to the motion of the body.
