What is the work energy theorem?

The formula for net work is net work = change in kinetic energy = final kinetic energy - initial kinetic energy. ... The work energy theorem, this is a theorem that states the net work on an object causes a change in the kinetic energy of the object. read more

The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object's kinetic energy. This principle of work and its relationship to kinetic energy is a core mechanical physics concept. read more

The Work-Energy Theorem 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. read more

This is our complete Work-Energy theorem. It is powerfully simple, and gives us a direct relation between net work and kinetic energy. Stated verbally, the equations says that net work done by forces on a particle causes a change in the kinetic energy of the particle. read more
