When you shake a tree, fruits fall because of ________.
Gravity and Inertia of rest
Correct Answer: Gravity and Inertia of rest
When a tree is shaken:
- The branch is accelerated (back and forth) by the external force.
- The fruit, due to inertia of rest (Newton's 1st Law), tends to remain in its original position and does not immediately follow the branch's motion.
- This relative movement causes the fruit's stalk to break.
- Gravity then pulls the fruit downward.
Inertia of motion would apply if the fruit was already in motion — which is not the case here. The fruit is initially at rest relative to the tree before shaking begins.
