By definition we have that the energy at the top of the ramp is equal to the energy at the bottom of the ramp. This is due to the principle of energy conservation.
We have then:
The energy at the top is only potential energy:
Where,
- <em>m: mass </em>
- <em>g: acceleration of gravity </em>
- <em>h: vertical height of the ramp </em>
The energy when it falls is transformed into kinetic energy and therefore:
Where,
- <em>v: object speed. </em>
Therefore we have:
Answer:
The potential energy is transformed into kinetic energy.
