Question

Define the following terms with SI units

a) Power

b) Energy

c) Work

Answer 1

Hi friend ,

(a). Power is defined as the rate of doing work or the rate of change of energy.

The SI unit of power is watt(W) .

1 watt is the power of an agent ,which does work at the rate of 1 Joule per second.


(b) Energy is referred to the capability to do work. An object having the capability to do work is said to possess energy.

The SI unit of Energy is Joule (J).

1 J is the energy required to do 1 joule of work.


(c) Work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force .

The SI unit of work is Joule ( J).

1 J is the amount of work done on an object when a force of 1 N displaces it by 1 m along the line of action of force .

Answer 2

1) power:- power is defined as the rate of doing work.
it's SI unit is watt (W).
1 watt of power is said to be done when 1 joule of energy is consumed per second.
1 joule/1 second.

2) energy:- an object posses energy if it has the capability to do work.
it's SI unit is joule.
1 joule is the energy required to do 1 J of work.

3) work:- work is said to be done when force produces displacement in the body.
SI unit is joules (J).
1 J is the amount of work done when a force of 1 N is applied on it.
