Question

A rider on a horse back falls forward when the horse suddenly stops. This is due to(a) inertia of horse(b) inertia of rider(c) large weight of the horse(d) losing of the balance

Answer 1

A rider on a horse back falls forward when the horse suddenly stops. This is due to (b) inertia of rider.

Concept:

Let us consider a case where a person is riding on the back of a running horse.

• Hence , both the rider as well as the horse are in motion.

• When the horse suddenly stops, the rider it is not in contact with the ground.

• As a result of this sudden stopping of the horse the rider falls forward due to his inertia of motion.

• Similar case is observed in passengers travelling in a bus, and the bus suddenly stops. All the passengers fall forward.

Answer 2

A rider on a horse back falls forward when the horse suddenly stops. This is due to (b) inertia of rider.

• When the horse suddenly stops, the rider falls in the forward direction due to the inertia of motion.
• As the body of rider tends to be in its original state when the horse suddenly stops, the lower body part of rider stops with the horse but, whereas the upper part remains in motion.
• So, the rider falls forward. This can be explained by Newton's law of motion.
• When the horse stops, the rider still has the inertia of motion, so he falls forward.
