Question

Which label of the roller coaster is incorrect?(1 point)ResponsesThe roller coaster would only have kinetic energy at the point labeled "gravitational potential energy and kinetic energy" because it will be accelerating at this point. The roller coaster would only have kinetic energy at the point labeled "gravitational potential energy and kinetic energy" because it will be accelerating at this point. The label indicating "maximum gravitational potential energy" because this should be at the lowest point on the track. The label indicating "maximum gravitational potential energy" because this should be at the lowest point on the track. The point labeled "maximum kinetic energy" because this is not the lowest point on the track. The point labeled "maximum kinetic energy" because this is not the lowest point on the track. The roller coaster would only have potential energy at the point labeled "gravitational potential energy and kinetic energy" because it is still above the ground at this point.

Answer 1

The label indicating "maximum gravitational potential energy" because this should be at the lowest point on the track.

Answer 2

Yes, the potential energy is MINIMUM (not maximum) where the altitude is minimum.

(m g h), small h is small U

Answer 3

You are correct. The label indicating "maximum gravitational potential energy" is incorrect because the potential energy is actually at its minimum at the lowest point on the track. Thank you for pointing that out.
