*of a body. Then a question arises that what is the work energy theorem is all about and how we can understand it.*

**work and kinetic energy**It is extremely easy to understand. We can understand it in a simple manner. For this sake of purpose; let we study the complete derivation or

**proof of work energy theorem.**

*Equation of work energy theorem*We derive the work energy theorem by following the equation of work.

Let we consider in general;

an object of mass ‘m’ is applied by a force ‘f’ which displaced it by a displacement ‘s’

Then amount of work done will be given by the equation of work.

Hence;

*work= force x displacement*

w=f x sw=f x s

Now, consider that an object get displaced by

Work energy theorem:

Now my question is the does the same concept get applied in space?

Please share your knowledge.

Now, consider that an object get displaced by

*. During this the amount of work will be***‘ds’****‘dw’**

It is for very small amount of work.

Now, the total work done by force is given by;

=final K.E.- Initial K.E.

=Change in Kinetic EnergyIt is for very small amount of work.

Now, the total work done by force is given by;

=final K.E.- Initial K.E.

=Change in Kinetic Energy

Work energy theorem:

Read more:Statement: from the above equation the work energy principle can be stated as the work done by a force to displaced an object is equal to the change in its kinetic energy.
