Question

A person is riding a skateboard on a U-shaped ramp. At which point does the person have the greatest potential energy?(1 point)
Responses

at the top of the ramp before they begin moving down into the ramp
at the top of the ramp before they begin moving down into the ramp

in the middle of the ramp at its lowest point in the U
in the middle of the ramp at its lowest point in the U

on the other side of the ramp as the person is coming back up
on the other side of the ramp as the person is coming back up

on the first part of the ramp as the person is moving down the side

Answer 1

The person has the greatest potential energy **at the top of the ramp before they begin moving down into the ramp**. At this point, they are at the highest elevation, and potential energy is maximum at the highest points in a gravitational field.
