4. Two objects are being lifted by a machine. One object has a mass of 2 kg, and is lifted at a speed of 2 ms. The other has a mass of 4 kg and is lifted at a rate of 3 ms.
a. Which object has more kinetic energy whule it is being lifted?
b. What does this tell you about the variable(s) that impact kinetic energy?
c. Which object had more potential energy when it was lifted a distance of 10 m?
d What does this tell you about the variable(s) that impact gravitational potential energy?
