There is a strong connection between work and energy in a sense that when there is a net force doing work on an object the object s kinetic energy will change by an amount equal to the work.
Work energy theorem definition physics.
For an object traveling at a speed v and with a mass m the kinetic energy is given by.
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.
The physics definition of work is.
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.
The work energy theorem is useful however for solving problems in which the net work is done on a particle by external forces is easily computed and in which we are interested in finding the particles speed at certain positions of even more significance is the work energy theorem as a starting point for a broad generalization of the concept.
The work energy theorem can also be applied to an object s potential energy which is known as stored energy when a skier waits at the top of the hill before taking off they have potential.
Review the key concepts equations and skills for the work energy theorem.
This principle of work and its relationship to kinetic energy is a core mechanical physics concept.
