What happens when there is a n increased height for a ball dropping?

• There is less potential energy from an increased height, which results in greater speed as it drops.

• There is a greater potential energy from an increased height, which results in greater speed as it drops.

• There is a greater potential energy from a decreased height, which results in greater speed as it drop.

• There is less potential energy from an increased height, which results in a slower speed as it drops.
