JEE Exam » Difference Between » Work and Energy

# Work and Energy

Work and Energy both come from the same place and are related to one another. Essentially, work is energy that has been transferred from one object to another. Furthermore, the two terms can be used interchangeably, but in some cases, it is more efficient or helpful to use one term over the other. However, if you do need a definition of work or energy, there are several on this site that are listed below.

## Energy:

Energy is defined as the ability of an object to do work. Work is defined as a force acting on an object over a part of its surface resulting in a displacement of the object over a distance. It is also known as mechanical energy and kinetic energy. Work and Energy can be converted from each other.

Formula for Energy:

K.E.=1/2×m×v2

where,

K.E.- Kinetic Energy

m- Mass of the object

v- The velocity of the object

Significance of Energy:

Simply put, energy is the source for all of our technology. The reason why we are using so much energy does not have to do with us looking for a new energy source; it is because we have been studying and practicing ways to obtain it from other sources. Furthermore, an enormous amount of energy is required every day by us and in our society. We use up more than half of the total amount of total world energy every year.

## Application of Energy:

It is used in a variety of ways that include lighting, heating, and communications. The amount of energy we use nowadays is growing every day and it continues to grow as we continue to develop technology. Energy is the life for all the machines that keep us going and the reason why humans have been able to live forever and live on other planets.

Work:

Work is defined as force acting on an object through a distance over a period of time to produce a displacement. Work is caused by the transfer of energy. Work also can be used interchangeably with energy and many times there is no difference in using one over the other. However, in some cases it is more efficient or helpful to use one term over the other.

## Formula for Work:

W=F.d

W=F.d.cos θ

Where,

F- force applied

d- displacement

θ- the angle between force and direction of motion

Work can be produced by a force acting on an object using a displacement that is perpendicular to that force.

## Difference between work and energy:

Difference between Work and Energy:

1) Work is force acting over a surface causing a displacement perpendicular to the force.

2) Energy is defined as the ability of an object to do work.

3) Work and Energy can be converted from each other.

4) Energy is the source for all of our technology.

5) Work can be produced by a force acting on an object using a displacement that is perpendicular to that force.

## Conclusion:

Work and Energy are both used in many different ways, but they have several similarities that make them interchangeable. Whether you need a definition of work or energy, this article will help you find the information that you need throughout the site. Therefore, if you are looking for a definition of work or energy, this article is right for you. Work is what makes our lives go by and why we are able to keep living. Work is basically force applied to something over a surface; it will show up as a displacement on an object. The more force there is, the more work will be produced. Finally, work can be converted from energy as well as other forms of energy such as heat or electricity.
