Question

A man getting down from a running bus falls forward :

• A. as the forward movement of bus tries to pull the man forward
• B. due to inertia the upper part of the body moves in the forward direction while feet come to the rest as soon as they touch the road
• C. as he leans forward as a matter of habit
• D. due to the combination effect of all the three factors stated in $\left(A\right),\left(B\right)$ and $\left(C\right)$

Answer 1

The correct option is B due to inertia the upper part of the body moves in the forward direction while feet come to the rest as soon as they touch the road

Inertia is the tendency of an object to resist any change in their state of motion. When a person alights from the bus, his body would try to continue moving in the direction the bus was moving due to inertia. But as soon as both the feet touches the ground, the lower part of the body comes to rest while the upper part gets carried away under the effect of inertia resulting into his forward fall.
