A10 kg rock is suspended 320 m above the ground.
calculate the potential energy of the rock before it is released.
p. e. =
1.6 x 104 j
3.1 x 104 j
3.1 x 107 j
1.0 x 107 j

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
