Question

In which scenario below does the ball have more gravitational potential energy when sitting at the top? Why?

Answer 1

Explanation : The scenario when the ball have more gravitational potential energy when sitting at the top are :-

• The gravitational potential energy is converted to kinetic energy during the negligible air resistance .

• However in the presence of the air resistance the ball will move very fast   . because it will gain all the gravitational potential energy during free fall of the ball
• the ball will have less kinetic energy when it will be pushed against the gravitational force . the velocity at which this occurs is called the terminal velocity .
