The kinetic energy in the work-energy theorem is specifically the translational kinetic energy of a mass moving at a:
AGiven speed
BGiven angle
CGiven height
DGiven colour
Answer & Solution
Correct answer: A. Given speed
1. Kinetic energy is defined from mass and motion.
2. The net work on a system equals the change in kinetic energy.
3. That quantity is defined to be the translational kinetic energy of a mass.
4. It is the kinetic energy of a mass moving at a speed.
