Websource. Like potential energy, kinetic energy has two primary types: in this case, translational kinetic energy and rotational kinetic energy. The translational kinetic energy of an object is the amount of work it requires to take that object from its resting position to a required velocity, e.g., accelerating a parked car to 50 miles per hour. . Translational … WebNov 5, 2024 · Kinetic Energy: A force does work on the block. The kinetic energy of the block increases as a result by the amount of work. This relationship is generalized in the work-energy theorem. The work W done by the net force on a particle equals the change in the particle’s kinetic energy K E: (6.4.1) W = Δ K E = 1 2 m v f 2 − 1 2 m v i 2.
