NOTES ON KINETIC ENERGY AND WORK-ENERGY THEOREM212Kmv=Kinetic Energy netfiwKKK=−=∆Work-Energy Theorem a) Kinetic energy is energy associated with the motion of a particle. b) The SI unit of KE is the joule (J). c) The Work-Energy Theorem is valid even when the net force is not constant! d) The Work-Energy Theorem is valid only for particle-like objects. e) If work is done on a system and the onlychange in the system is in its speed, the work done by the net force equals the change in KE of the system!
