Question

If a green ball is higher from the ground than a yellow ball and both have the same mass,
which ball has more potential energy?
​

Answer 1

Answer:

The green ball has more potential energy.

Concept:

Potential Energy: The energy in an object due to the virtue of its position is called its potential energy. Mathematically, it can be expressed as follows

P.E. = mgh

where P.E. = Potential Energy

m = Mass of the object

g = Acceleration due to gravity

h = Height of the object

The SI unit of potential energy is joule (J).

Given:

Two balls = Green ball and yellow ball

Mass of both balls is same. Let it be m.

Height of green ball is more than that of yellow ball.

Let height of green ball be H and that of yellow ball be h where H>h.

Solution:

Potential Energy of green ball is given by,

P1 = mgH

Potential Energy of yellow ball is given by,

P2 = mgh

As we know, H > h

As a result, P1>P2

Hence, Green ball has more potential energy.
