An athlete runs a short distance before taking a long jump. Which type of inertia helps the athlete jump farther?
AInertia of rest
BInertia of direction
CInertia of gravity
DInertia of motion
Answer & Solution
Correct answer: D. Inertia of motion
1. While running, the athlete's body is in a state of motion.
2. At the jump, the body tends to continue in that state of motion.
3. This resistance to changing the motion state is inertia of motion, carrying the athlete farther.
