Question

reflection: when the marble was released, it rolled down the ramp and transferred energy to the cup. this transfer of energy is what makes the cup move. but where did the marble get the energy from? the marble got its energy from________. i say this because________.

Explanation:

The marble initially has gravitational - potential energy due to its height on the ramp. As it is released and rolls down, this potential energy is converted into kinetic energy.

Answer:

The marble got its energy from its initial height on the ramp (gravitational - potential energy). I say this because when an object is at a certain height in a gravitational field, it has stored potential energy which is converted to kinetic energy as it moves downwards.
