Answer 1

$\huge\bf\red{ \mid{ \overline{ \underline{ANSWER}}} \mid}$

$\sf\small\purple{Potential \: energy}$

Potential energy, stored energy that depends upon the relative position of various parts of a system.

$\sf\small\pink{Derivation \: for \: the \: equation \: of \: Potenstial \: Energy:}$

Let the work done on the object against gravity = W Work done,

⟶W = force × displacement Work done,

⟶W = mg × h Work done,

⟶W = mgh

Since workdone on the object is equal to mgh, an energy equal to mgh units is gained by the object .

Answer 2

Explanation:

Potential energy is the work done to take a body to a certain height. For a body with mass m, h is the distance to which it is raised and g is the gravitational force acting on the body, then work done W is given as: W = force * displacement. W = mg * h. ∴ W = mgh.
