Question

If 20 joule work is done on a body what
will be gain
in kinetic energy​

Answer 1

Given:

20 joule work is done on a body.

To find:

Gain in KE?

Calculation:

In these types of questions, simply apply WORK-ENERGY THEOREM.

• Work-Energy Theorem states that the total amount of work done by all the forces on an object is equal to the change in kinetic energy of that object.

Following the above definition, we will say:

$\boxed{ \bf W = \Delta KE}$

$\sf \implies \Delta KE = 20 \: joule$

So, gain in kinetic energy is 20 Joule.

Answer 2

Given:-

20 joule work is done on a body.

To Find:-

Gain in KE?

Calculation:-

In these types of questions, simply apply WORK-ENERGY THEOREM.

• Work-Energy Theorem states that the total amount of work done by all the forces on an object is equal to the change in kinetic energy of that object.

Following the above definition, we will say:

W=ΔKE

⇒ΔKE=20 joule

So, gain in kinetic energy is 20 Joule.
