Types of Energy
Besides kinetic and potential energy, some other important types of energy are as follows:

What is Energy?
The capacity of a man that allows him to do work is called energy. In simple words, energy is the ability to work. It is in scalar quantity and has only magnitude and no direction. energy can neither be created nor destroyed, it can only change in its form. Energy can be found in many…

What is Work?
Work happens when a force makes something move. For example, when a person climbs a mountain, work is being done because they are going against gravity to go up. So, two things matter for work: To calculate work, you multiply how far something moves by the force acting on it. Work is just a number,…

Concepts of Work, Energy and Power for JEE Main Physics
This chapter will teach us about concepts like work, energy and power. Work, energy and power are essential concepts in physics. Work is the displacement of an object caused by a force (push or pull). Energy is defined as the ability to perform work. We also get to know about the work done formula and…

Definitions, Equation & Examples
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. The SI unit of moment of a force is Newton-metre (Nm). It is a…

Examples of Questions Solved with the Help of Angular Velocity (or speed) Formula Example 1:- Earth takes a whole year (365 days) to complete a single revolution around the sun. Calculate the angular speed with which the earth is rotating around the sun. Solution: The plane earth requires a full year to make a single…

Conversion of Degree to Radian and Radian to Degree.
The angle of rotation is often measured in the unit called the radian. (Radians are dimensionless units and are defined as the ratio of two distances, radius and arc length.) One complete revolution around the circumference of a circular object covers 2π radians or 360o in degree. Radian and degree are interconvertible and we can…

Formula of Angular Speed
The linear speed at which we already have a point on an object which is rotating depends on its distance from the centre of rotation. The angular speed which we know is the angle that an object generally moves through in a certain amount of time. The angular speed has units of radians per second…

How to Find Angular Speed
The speed which is known as the angular speed is the measure of how fast the central angle of a rotating body changes with respect to time. Angular speed formula is the relationship between angular speed and the speed which is linear along with a few angular speed problems. The term speed that is used…
