1. Does the bowling ball have more potential energy or kinetic energy as it sit on top of the building? Why?

Answer:

I think it has more potential energy because the ball has yet to move from it's spot.

The bowling ball have more gravitational potential energy as it sit on top of the building

Explanation:

The energy that is possessed by an object due to the position of that object in the field of gravity is called Gravitational potential energy. The object that is present in the place that is very closer to the Earth's surface has a constant gravitational potential energy. When an object is at certain height there is a necessity of force for lifting that object form that height.

This is applies to the gravitational potential energy also. When two objects are placed at different heights, the object that is placed at the greater height will have more potential energy. This is because, the force necessary to take the object from greater height will be more.
