Question

A car on a roller coaster track, launched by a huge spring, makes it to the top of the loop with some speed

a) Kinetic into Gravitational Potential
b) Spring Potential into Kinetic
c) Gravitational Potential into Kinetic
d) Spring potential into kinetic and gravitational potential

Answer 1

c) Gravitational Potential into Kinetic.

Step-by-step explanation:

When the car is launched by the spring, it gains potential energy due to the compression of the spring. As the car moves along the track and reaches the bottom of the loop, this potential energy is gradually converted into kinetic energy. At the top of the loop, the car has reached its maximum height and has gravitational potential energy with respect to the ground. As the car falls from the top of the loop, the gravitational potential energy is converted into kinetic energy.

Therefore, the energy transformation that occurs when the car is launched by the spring and makes it to the top of the loop is from Gravitational Potential Energy to Kinetic Energy.
