Work, Power and Energy

This topic deals with the concept of work and energy via examples. We will come across the formula of work done by a constant and variable force. It also covers the law of conservation of energy, along with a brief on the units of work and energy.

In this topic, we will learn about the time rate at which work is done or energy is transferred i.e. power. It also explains its SI unit, and derivation of formula along with instantaneous power.

Through this topic, we will understand the concept of kinetic energy in detail. We will derive the formula of kinetic energy here. It also discusses the statement of the work-energy theorem and explains how work depends on the change in kinetic energy.

In this topic, we will discuss the concept of conservative and non-conservative forces with examples. We will calculate the work done by both the forces here. It also explains how the central force is considered as a conservative force.

In this topic, we will learn the concepts of potential energy of an object. We will also derive its formula by taking the example of gravitational potential energy and work done by a conservative force.

In this topic, we will learn the conservation of mechanical energy. It also consists of the mathematical formula for it and brief on conservative force.

This topic discusses the different forms of energy. It also explains the principle of conservation of energy along with examples and formulas.

The topic discusses the types of collisions. It also explains collision in one and two dimensions with the help of figures and examples.
