Question

If acc. due to gravity is 10m/s^2 what will be the potential energy of a body of mass 1 kg kept at a height of 5 m

Answer 1

Answer :

• The potential energy of the body is 50 joule.

Given :

• Gravity = 10 m s¯¹

• Mass = 1 kg

• Height = 5 m

To find :

• The potential energy of the body =?

Step-by-step explanation :

We know that, the potential energy of a body is calculated by using the formula :

Potential energy = m x g x h

In this case, mass, m = 1 kg

Acceleration due to gravity,

g = 10 m s¯²

and, height, h=5 m

So, putting these values in the above formula, we get

Potential energy = 1 x 10 x 5

= 50 J

Thus, the potential energy of the body is 50 joule.

Answer 2

_______________________________

According to the Question

❍ Given:-

⋄ Acceleration due to gravity (g) = 10m/s²

⋄ Mass of the body (m) = 1kg

⋄ Height of the body ( h) = 5m

❍ To Find:-

⋄ Potential energy of the body (P. E)

❍ Solution :-

➧Potential Energy = mgh

➧P. E.= 1×10×5

➧ P. E=50Joule.

∴The Potential Energy of the body is 50J.

✰Extra Knowledge :-

➧ The energy of an object because of its position or shape is called its potential energy.

➧ P. E. =mgh

where

m is the mass of object

g is the acceleration due to gravity

h is the height of object
