Work, Energy and Power

This topic helps us understand the scalar product of two quantities. This concept is explained through illustrations and examples for a better understanding.

This topic relates the energy of a system or particle with the work associated with it. It showcases the derivation for the work-energy theorem in detail along with some solved questions to make us understand it better.

In this topic, we will learn the concept of work. Units and formulas of work are also discussed here. We will come to know about different instances when the work is said to be done.

This topic elaborates on the kinetic energy of an object. It also explains units and formulas for kinetic energy. Afterwards, we will encounter some solved examples to understand this concept better.

This topic explains work done by a variable source with the variation in displacement. It also describes mathematical proof for it along with proper illustrations and examples.

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.

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.

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