# What is the definition of Force and energy We know that energy, force, mass, gravity, vectors, scalars are some of the fundamental concepts of Physics, which lets us understand science in a better way. Learning and understanding the basic concepts is a vital part of any study. Let us know in detail about energy and types of energy in this article. Energy is an essential element of living and can be felt everywhere around us.

## What is Energy?

Energy is described as the capacity for doing the work. There are many direct and indirect sources of energy that can be seen around us. For example, sunlight is the direct form of energy and food that we consume is an indirect source of energy. The unit of energy is Joule.

Joule is a derived unit that is equal to the energy expended in applying a force of one newton through a distance of one meter. The name joule was named after the great English physicist, James Joule who developed the first law of thermodynamics. Energy can also travel in the form of electromagnetic waves like light, gamma rays, radio, and heat.

As per the law of conservation of energy, it is stated that “Energy can neither be created nor destroyed but can only be converted from one form to another.”

There are different types of energy; they are:

• Kinetic energy
• Chemical energy
• Thermal energy
• Heat energy
• Potential energy
• Light energy
• Geo-thermal energy
• Hydroelectric energy
• Wave energy
• Green energy
• Biomass energy
• Kinetic energy
• Tidal energy
• Nuclear energy
• Wind energy

We shall also learn what is force and centripetal force definition now.

### Force – Type of Energy

The push or pull on an object with mass that causes it to change its velocity is known as force. Even actions like stretching and squeezing are termed as a force. Force is denoted by the symbol ‘F’, and its SI unit is Newton. Force is characterised with both magnitude and direction.

Force can make a body that is at rest to move. It can also change the direction of a moving body. The body can undergo a change in shape and size when a force acts on it. Force can slow a moving body or can stop it. As per the need, the force can accelerate the speed of a moving body.

Example: Magnetic force, Gravitational force, Frictional force, Electric force and Nuclear force.

Force acts on an object in two types, in curvilinear motion, i.e., centrifugal force and centripetal force. Centripetal Force Definition is as follows, the force acting on an object in curvilinear motion which is directed toward the axis of rotation or centre of curvature is known as centripetal force.

Example: planets orbiting around the sun.

Centrifugal Force Definition is as follows, the force that arises from the body’s inertia and appears to act on a body that is moving in a circular path which is directed away from the centre around which the body is moving.

Example: When an object tied at the end of a string is whirled in a horizontal circle.

Hope you understood and learnt the Centripetal Force Definition along with examples. Previous article
