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.

Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
In this section we begin the study of various types of work and forms of energy. We will find that some types of work leave the energy of a system constant, for example, whereas others change the system in some way, such as making it move. We will also develop definitions of important forms of energy, such as the energy of motion.
Explain work as a transfer of energy and net work as the work done by the net force. Explain and apply the work-energy theorem.
Use the work-energy theorem to find information about the forces acting on a particle, given information about its motion. We have discussed how to find the work done on a particle by the forces that act on it, but how is that work manifested in the motion of the particle?

27 maj 2024 · The principle of work and energy states that the work \(W\) done by a force \(\overrightarrow{\boldsymbol{F}}_{i j}\) on a point mass \(i\), while it moves along a path curve from position \(s_{1}\) to position \(s_{2}\), is equal to the change in its kinetic energy \(T_{i}\).
