Question

as this roller coaster car begins to go down, what is happening to the potential energy of the car? the energy is changing from potential energy to kinetic energy the energy is changing from kinetic energy to potential energy

Explanation:

Potential energy depends on height (\(PE = mgh\), where \(m\) is mass, \(g\) is acceleration due to gravity, and \(h\) is height). As the roller - coaster car goes down, its height \(h\) decreases. Kinetic energy (\(KE=\frac{1}{2}mv^{2}\), where \(v\) is velocity) increases as the car accelerates downwards. So, the energy transformation is from potential energy (due to height) to kinetic energy (due to motion).

Answer:

the energy is changing from potential energy to kinetic energy
