The total work done on a particle is equal to the change in its kinetic energy always
Explanation:
The working theory and kinetic energy (also known as the work-energy theorem) states that the work performed by the sum of all forces acting on a particle is proportional to the change in the particle's kinetic energy.
The theorem of work-energy can be derived from the second law of Newton. Work moves energy from place to place or form to form to shape. Research may change the potential energy of a mechanical device, the heat energy in a thermal system, or the electrical energy in an electrical device in more general systems than the particle system described here.The working and kinetic energy theory (also known as the working -energy theorem) states that the work done by the sum of all forces acting on a particle is proportional to the change in the particle's kinetic energy.
When describing the function of torque and rotational kinetic energy, this concept can be generalised to rigid bodies.
