Kim and karley are playing basketball. as they bounce the ball and shoot hoops, kim says that basketball is a great example of elastic potential energy. karley says that the game of basketball shows kinetic energy and gravitational potential energy. who is right and why? question 7 options: karley is right. when they throw the ball into the basket, it increases its potential energy because it is up high in the air. both girls are correct. the ball has elastic potential energy when it bounces, gravitational potential energy when it is in the air, and kinetic energy while it is moving. kim is right. as the ball bounces it compresses and then springs back to its original shape. neither girl is right. since the basket ball is constantly moving, it only experiences kinetic energy

Rita throws a ball straight up into the air and catches it at the same position from which she threw it. the ball has 18 j of mechanical energy when it leaves her hand. if no energy is lost due to friction, which statements about the energy of the ball are true? check all that apply. the potential energy at the top of the ball’s motion is 18 j. the kinetic energy is less when the ball is thrown than when it is caught. the kinetic energy increases as the potential energy decreases. the kinetic energy decreases as the potential energy increases. the total mechanical energy of the ball stays constant. the mechanical energy decreases as the ball moves up and increases as the ball comes down.
