PLEASE HELP ( I put the other pic because i didn’t know if that was needed for those two questions)

1. The skater's kinetic energy decreases as he moves up the ramp. As the skater moves down the ramp, his potential energy decreases

2.Kinetic Energy is the energy of motion. As the skateboard rolls down the ramp it loses potential energy and gains kinetic energy. The total energy of the skateboarder remains constant.
