Question

work,energy and power

Answer 1

Work:

It can be also be defined as the transfer of energy. In physics the work is done on an object when the energy transfer to that object. If one object transfers (gives) energy to a second object, then the first object does work on the second object.

OR

Work is done when a force applied to an object moves that object.

Mathematically,

Work = {Force* displacement} Joule

Energy:

The capacity to do work is known as energy.

Types of energy:

Kinetic Energy = Energy of Motion

Potential Energy = Stored Energy

The SI unit of energy is Joule.

Power:

The rate or work done is known as power.

OR

The work done per unit time is known as power.

The SI unit of the power is {J/s = Watt}
