Consider the ball rolling down the ramp which graph represents the change in potential and kinetic energy

Top of the ramp = Potential energy at its highest, kinetic energy at its lowest

Middle of the ramp = Both are equal

Bottom of the ramp = Kinetic energy at its highest, potential energy at its lowest

Step-by-step explanation:

When the ball is at the top of the ramp, potential energy is at it's highest, while kinetic energy is at it's lowest. As the ball rolls down the ramp, potential energy decreases while kinetic energy increases. At the middle of the ramp, potential and kinetic energy are equal. At the bottom of the ramp, the ball moves fastest, while kinetic energy it at it's highest and potential energy is at it's lowest.
