What is your prediction 1-2? How will kinetic energy, gravitational potential energy, and mechanical energy change as the ball falls?
a) Kinetic energy increases, gravitational potential energy decreases, mechanical energy remains constant
b) Kinetic energy decreases, gravitational potential energy increases, mechanical energy remains constant
c) Kinetic energy decreases, gravitational potential energy decreases, mechanical energy increases
d) Kinetic energy increases, gravitational potential energy increases, mechanical energy remains constant
