unit 8 conservation in systems exam - ma\na roller coaster at rest at the top of the track has ____ energy.\n○ kinetic energy\n○ exactly equal amounts of kinetic and potential energy\n○ potential energy

unit 8 conservation in systems exam - ma\na roller coaster at rest at the top of the track has ____ energy.\n○ kinetic energy\n○ exactly equal amounts of kinetic and potential energy\n○ potential energy

Answer

Brief Explanations:

Kinetic energy depends on motion ($KE=\frac{1}{2}mv^2$); since the coaster is at rest ($v=0$), it has no kinetic energy. Potential energy depends on position/height, and the coaster at the top of the track has stored gravitational potential energy.

Answer:

potential energy
