Question

A man getting down a 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 they 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

The correct option is 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 they touch the road

See Newton’s first law of motion according to which “the tendency of a body to continue in its state of rest or of uniform motion in a straight line, is called law of inertia”.
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 they touch the road.
