Question

Potential energy of an object raised through a height $h$ is ……… ($1/2m{v^2},mgh$)

Answer 1

Hint: The ability to do any work is known as energy. It may exist in potential, kinetic, chemical, nuclear or other form of the energy. Energy has various types but they all fall in two categories- kinetic energy and potential energy. Energy can be classified on the basis of source- renewable source energy and non-renewable source energy. The SI unit of energy is Joule and it is denoted by ’J’. As we know that potential energy is
$ \Rightarrow U = F \times h$

Complete answer:
Potential energy is energy that an object has because of its position relative to the other objects. It is also known as stored energy.
Let us assume any object with mass ‘m’, is lifted in an upward direction up to sudden height ‘h’. So the potential energy can be calculate for:
$ \Rightarrow U = F \times h$
Here, U= Potential energy
F= Force applied in object to lift upward
h=height of an object.

$ \Rightarrow F = m \times g$
‘g’ is acceleration due to gravity.
Put the value in the equation.
So the potential energy is given by,
$ \Rightarrow U = m \times g \times h$
So the answer to the question is mgh.

Note: Energy is a conserved quantity and obey the law of conservation of energy. Law of conservation of energy states that the energy can neither be created nor be destroyed, it can be transferred from one form to another. Potential energy totally depends on the position of the object if there is not any height or h=0. Then potential energy will be Zero (0).
