Question

If you have a mass of 80 kg and you are standing on a platform 3 m above the ground, what is your gravitational potential energy?

Answer 1

Answer:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Answer 2

Answer :-

2352J

Explanation :-

Given :

Mass,m => 80kg

Height,h => 3m

Gravitational acceleration,g => 9.8m/s^2

To Find :

Gravitational potential energy,PE = ?

Solution :

We know,

$\sf{}PE = mgh$

$\sf{}\implies 80kg\times 9.8m/s^2\times 3m$

$\sf{}\therefore 2352J$

Therefore,gravitational potential energy is equal to 2352J

Additional knowledge :-

The gravitational potential energy of an object is defined as the work done in raising the object from ground to the given height against gravity.SI unit of gravitational potential energy is (J) Joule.

For example; when a stone is kept at a height, it possesses some energy because of its height. Because of this potential energy, object kept at a height falls over the ground.

Formula for gravitational potential energy,

$\boxed{\sf{}PE = mgh}$

Potential energy = Mass x acceleration due to gravity x height
