Answer

NCERT Solutions - Work and Energy

Below are the detailed solutions for the NCERT textbook questions related to Work and Energy:

Definition of Work and Energy

Work: Work is done when a force acts on an object and displaces it in the direction of the force.
Energy: Energy is the ability to do work. It exists in various forms such as kinetic, potential, and mechanical energy.

Work-Energy Theorem

The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.
Mathematically, W = ∆KE, where W is the work done and ∆KE is the change in kinetic energy.

Types of Energy

Kinetic Energy: The energy possessed by a moving object is called kinetic energy and is given by KE = 1/2 * mv^2.
Potential Energy: The energy stored in an object due to its position or state is called potential energy and is given by PE = mgh.

Conservation of Energy

The law of conservation of energy states that energy can neither be created nor destroyed, it can only be transformed from one form to another.
Therefore, in a closed system, the total energy remains constant.
