Question

An athlete can take a longer jump if he comes running from a large distance. Identify the type of inertia at the time of jump.

• A. Static Inertia
• B. Dynamic Inertia
• C. Both static and dynamic inertia at the same time
• D. No inertia at the time of jump

Answer 1

The correct option is B Dynamic Inertia

Just before the jump, the athlete is in motion. At the time of the jump, the dynamic inertia (Inertia due to motion) of the body keeps him pushing further. As a result, the athlete can take a long jump. Hence, the inertia at the time of jump possessed by the athlete is dynamic inertia.
