Question

what is work and energy ??​

Answer 1

The principle of work and kinetic energy (also known as the work–energy principle) states that the work done by all forces acting on a particle (the work of the resultant force) equals the change in the kinetic energy of the particle.

Answer 2

Answer:

Work and energy

Work is closely related to energy. The work–energy principle states that an increase in the kinetic energy of a rigid body is caused by an equal amount of positive work done on the body by the resultant force acting on that body.

SI unit: joule (J)

In SI base units: 1 kg⋅m2⋅s−2

Derivations from other quantities: W = F ⋅ s; W = τ θ

Other units: Foot-pound, Erg
