Overview of the course

This lesson explains what do you mean by work in physics. It explains how we can calculate the work done by a body. At last , some numerical problems related to work are discussed.

Work

This lesson explains what do you mean by energy. Then the kinetic energy is discussed and some numerical problems related to it are solved.

Kinetic Energy

This lesson explains the gravitational and elastic potential energy. In this lesson , we also derive the formula of gravitational potential Energy and solve some sample problems.

Potential Energy

In this lesson, we discuss what is meant by power and what are the units of power. Then we discuss the commercial unit of Energy and discuss some sample problems related to these topics.

Power

In this lesson, we discuss the energy transformations that take place in a hydroelectric power house and a thermal power house. Then we discuss the energy transformations in day to day appliances and gadgets.

Transformation of Energy

In this lesson , the law of Conservation of Energy is explained by the example of a freely falling body and a simple pendulum.
