The quantity \(\frac{1}{2}mv^2\) in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass \(m\) moving at a speed \(v\). ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.)

- 6.4: Work-Energy Theorem
Kinetic energy is a form of energy associated with the motion of a particle, single body, or system of objects moving together. We are aware that it takes energy to get an object, like a car or the package in Figure 7.4, up to speed, but it may be a bit surprising that kinetic energy is proportional to speed squared. This proportionality means ...
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.
Learn about the concepts of work and kinetic energy in physics, with definitions, formulas, examples, and exercises. Explore the work-energy theorem, power, and the relationship between work and force.
In this chapter we will be concerned with mechanical energy, which comes in two forms: kinetic energy and potential energy. Kinetic energy is also called energy of motion. A moving object has kinetic energy.
Learn about kinetic energy and work in one, two and three dimensions, and how to apply the work-kinetic energy theorem and the concept of conservative and non-conservative forces. Watch videos, read lessons and problem sets from the MIT course 8.01SC.
Learn how work transfers energy to a system and how the net work is related to the change in kinetic energy of the system. Explore examples, graphs, and the work-energy theorem with proof and applications.
