If you roll a ball slowly on the ground, it will eventually stop. This is because _____________
kinetic energy is transformed to potential energy
the ball needs more thermal energy to keep going
kinetic energy is transformed to sound & thermal energy
the energy of the ground will reduce mechanical energy
When a ball is bouncing, the potential & kinetic energy change. The ball will eventually stop bouncing. This is because __________.
the balls energy is transformed to chemical energy
the balls energy is transformed to heat and sound energy
the mass of the ball is too small so it cannot continue in motion
the pull of gravity is stronger than the energy of the ball
