An ice hockey player hits a stationary puck with a stick, and the puck then slides along horizontal ice. Which statement explains how the puck gains energy while the stick is in contact with it?
The force from the stick does work on the puck, so energy is transferred to the kinetic store of the puck.
The force from the stick does work on the puck, so energy is transferred to the gravitational store of the puck.
The stick heats the puck, so energy is transferred to the kinetic store of the puck.
The stick heats the puck, so energy is transferred to the gravitational store of the puck.
