Suppose you toss a tennis ball upward.
(a) Does the kinetic energy of the ball increase or decrease as it moves higher?
(b) What happens to the potential energy of the ball as it moves higher?
(c) If the same amount of energy were imparted to a ball the same size as a tennis ball but of twice the mass, how high would it go in comparison to the tennis ball? Explain your answers.
