A toy car is released from rest at the top of a ramp. The car speeds up as it moves down the ramp. When it reaches the bottom of the ramp, the toy car rolls across the floor and eventually stops. Which two statements identify evidence that energy was conserved? A. As the car rolls down the ramp, it speeds up because gravitational potential energy is transformed into kinetic energy. B. As the car rolls down the ramp, it speeds up because thermal energy due to friction is transformed into kinetic energy. m C. As the car rolls across the floor, it stops because its kinetic energy is transformed into gravitational potential energy, 1 D. As the car rolls across the floor, it stops because its kinetic energy is transformed into thermal energy due to friction
