Two objects are being lifted by a machine. One object has a mass of 4 kg, and is lifted at a speed of 5 m/s. The other has a mass of 8 kg and is lifted at a rate of 7 m/s. Which object had more potential energy when it was lifted a distance of 10 m? What does this tell you about the variable(s) that impact gravitational potential energy?
