When you vigorously shake the branch of a tree, ripe fruits fall down. This is an example of which type of inertia?
AInertia of motion
BInertia of direction
CInertia of weight
DInertia of rest
Answer & Solution
Correct answer: D. Inertia of rest
1. When the branch is shaken, it suddenly starts moving.
2. The fruits tend to stay at rest due to their resistance to changing the rest state.
3. This resistance to change from rest is inertia of rest, so the fruits detach and fall.
