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: -The mechanical energy of a free-falling body always remains to conserve during a free fall. For example, if you drop an object intentionally from your hand, you can observe that it will fall at a constant speed until it reaches the ground. So, we can say that its mechanical energy is constant in all instances.

Detailed explanation-5: -The law of conservation of mechanical energy states that the mechanical energy in a system remains constant as long as the forces applied are conservative(doesn’t depend on the path).
