PLEASE HELP WILL GIVE BRAINLIEST!! 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
C. As the car rolls across the floor, it stops because its kinetic
energy is transformed into gravitational potential energy.
D. As the car rolls across the floor, it stops because its kinetic energy
is transformed into thermal energy due to friction
