The gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.
<h3>
What is kinetic energy?</h3>
The kinetic energy of an object or body is due to its motion. When the roller coaster moves downhill it accelerates, thus the gravitational potential energy as a rollercoaster converts to kinetic energy.
The gravitational potential energy of an object or body is due to its position above the ground.
Therefore, the gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.

Answer:
1.5 Amp is rated for 5 W so it would not be possible
Answer:
Explanation:
Given
winning car accelerates with a and its final velocity is v
considering they both start from rest
time taken by winning car is
v=u+at
where u=initial velocity
a=acceleration
t=time
Now loosing car is accelerating with 
Distance traveled by loosing car in time t
Thus distance d traveled by loosing car is given by
Work is (force applied) x (distance through which the force moves).
Since the suitcase doesn't move up or down during the 15 minutes,
no work is done ... zero, zip, nada ... according to the real Physics
definition of 'work'.
