Question

explain the conversion of energy that occurs from \b\ to \c
potential to kinetic
kinetic to potential
both answers are correct
neither a or b are correct

Explanation:

Potential energy is related to height (\(PE = mgh\), where \(m\) is mass, \(g\) is acceleration due to gravity, and \(h\) is height). Kinetic energy is related to speed (\(KE=\frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is speed). From point \(B\) to \(C\), the height of the roller - coaster decreases. As height (\(h\)) decreases, potential energy (\(PE\)) decreases. According to the conservation of mechanical energy (neglecting non - conservative forces like friction for a basic analysis), the loss in potential energy is converted into kinetic energy. So the energy conversion is from potential to kinetic.

Answer:

potential to kinetic
