Question

state and explain work energy theorem​

Answer 1

Explanation:

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. ... This relationship is generalized in the work-energy theorem.

The work of the net force is calculated as the product of its magnitude (F=ma) and the particle’s displacement. Substituting the above equations yields:

W=Fd=mav2f−v2i2a=12mv2f−12mv2i=KEf−KEi=ΔKEW=Fd=mavf2−vi22a=12mvf2−12mvi2=KEf−KEi=ΔKE

Answer 2

Explanation:

Work energy theorem states that the change in kinetic energy of an object

is equal to the net-work done on it by the net force.
