What is the potential energy of a 3 kilogram ball this is on the ground?

zero. PE= mass*g*height

zero because potential energy can be calculate if object attaining some height

To determine the potential energy of an object, we need two pieces of information: the mass of the object and its height above a reference point. In this case, since the ball is on the ground, its height above the reference point is zero.

Potential energy is given by the equation PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height.

In this scenario, since the ball is on the ground, the height (h) is zero. Therefore, the potential energy of the ball is also zero.

In summary, the potential energy of a 3 kilogram ball on the ground is zero because its height above the reference point is zero.
