Which form of energy does a bowling ball have because it rolls toward the bottles?

Which form of energy is stored in the bent limbs of Paolo's drawn bow?

Which type of energy can sugar supply through reactions in the body?

A ball is falling and is still above the ground. Using the ground as the zero-height reference, which statement describes its energy?

A motorcycle's speed doubles while its mass stays unchanged. What happens to its kinetic energy?

Two carts travel at the same speed. One has twice the mass of the other. How does the heavier cart's kinetic energy compare?

A 280 g volleyball leaves Bea's hand at 30 m/s. What is its kinetic energy?

A 2 kg bag is held 5 m above the floor. Taking the floor as zero and $g=9.8{\text{ m/s}}^2$, what is its gravitational potential energy?

Ramon raises the same object from 2 m to 6 m above the floor. How does its gravitational potential energy relative to the floor change?

After leaving Ana's hand, a ball rises through the air. Ignoring air resistance, how do its kinetic and gravitational potential energies change?

Water falls over a waterfall and gains speed. How do its kinetic and gravitational potential energies change during the fall?

A cart starts from rest at A and follows the pictured track without friction. At which labeled point is its kinetic energy greatest?

At which labeled point would the same cart have the greatest gravitational potential energy relative to the ground?

The pictured pendulum bob is released from A. Ignoring air resistance, how does its speed change as it travels toward B?

How is an object's mechanical energy determined?

A ball has 40 J of kinetic energy and 60 J of gravitational potential energy. What is its total mechanical energy?

A cart travels along a track without friction, air resistance, or a motor. What happens to its total mechanical energy?

A dropped rubber ball rebounds to a lower height. What explains this result?

A ball falls from rest with negligible air resistance. If its release height above the ground is quadrupled, how does its speed just before impact change?

Liza lengthens a pendulum's string but keeps the same bob and vertical release height above its lowest position. Ignoring resistance, how does its maximum kinetic energy change?
