Question

In a roller coaster, both the kinetic and potential energy in the car decreases at

Answer 1

We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at  each successive hill because of  the force of gravity which converts potential  energy into  kinetic energy.

What are potential and kinetic energy?

• Potential energy is referred to as positional energy.
• This means that the object in question gains energy based on its position relative to others.
• Kinetic energy is the energy of movement.
• Gravity causes the roller coaster to fall, losing potential energy.
• This causes it to gain all of the potential energy as kinetic energy.
• Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.
