Question

Explain how the energy of a marble is transformed as it rolls down a ramp. Give evidence that energy of the marble remains the same at all points on the ramp. I need some help on this it is the last question on my test.

Answer 1

The marble is release from the top of the ramp.Gravitational potential energy decreases as it roll down the ramp,at the same time the marble gains kinetic energy as well as a lost of energy in the form of heat due to friction.

Chenge in PE=change in KE

therefore energy remains the same on all parts of the ramp

Answer 2

Answer:

I had to do that to

Explanation:

when the ball is not going down it has potential energy and when it does go down it is kenetic energy
