select the statement that accurately labels the diagram.
point a is the greatest ke, point b is the greatest pe, point c is ke.
point a is ke, point b is the greatest ke, point c is the greatest pe.
point a is the greatest pe, point b is the greatest ke, point c is pe.
point a is the greatest pe, point b is pe, point c is the greatest ke.

Explanation:

• Potential Energy (PE) is related to height. The higher the object, the greater its potential energy. Point A is the highest, so it has the greatest PE.
• Kinetic Energy (KE) is related to speed. The lower the height (converting PE to KE), the greater the speed (and thus KE). Point B is the lowest, so it has the greatest KE.
• Point C is at an intermediate height, so it has some PE (less than A) and some KE (less than B).

Answer:

Point A is the greatest PE, point B is the greatest KE, point C is PE.
