Question

What is the most likely evidence of an energy transformation taking place when a skater glides over ice? A.Skating blades become cold as kinetic energy is transformed into thermal energy B.Skating blades become cold as kinetic energy is transformed into gravitational energy C.Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy D.Small tracks of water are left on the ice as kinetic energy is transformed into gravitational energy

Answer 1

The correct answer is C. The weight downward and the friction moving forward creates thermal energy through kinetics and melts a tiny bit of the ice making it slick enough for the skate to slide.
