Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The mechanical energy of a coconut falling from a tree ____

A	doesn’t exist
B	increases
C	decreases
D	remains constant

Explanation:

Detailed explanation-1: -Energy conservation is applied to the system of a falling coconut. The total energy of the system remains constant. That means the sum of kinetic energy and potential energy should be constant.

Detailed explanation-2: -Solution: The form of energy possessed by a coconut falling from a tree is kinetic energy.

Detailed explanation-3: -Hence, when an object falls freely, its potential energy gets converted into kinetic energy. When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.

Detailed explanation-4: -Answer: A coconut falling from a tree is an example of gravitational motion. Hope it helps you.
