Question

the net work done by a net force acting on a object is equal to the change in the kinetic energy of the object

Answer 1

Answer:

The net work done on the object is equal to the change in the kinetic energy of the object. Wnet = Kf - Ki = ½m(vf2- vi2) = ∆K. This is called the work-kinetic energy theorem.

Answer 2

Answer:

The net work done by a net force acting on a object is equal to the difference between the final kinetic energy of the object and the initial kinetic energy of the object.

$W_{net}$ = $K$ - $K_{0}$ = Δ$K$.

Explanation:

The net work done by a net force acting on a object is equal to the difference between the final kinetic energy of the object and the initial kinetic energy of the object.

Let ,  $W_{net}$ is the net work done by a net force acting on a object , $K$ is the final kinetic energy of the object , $K_{0}$ is the initial kinetic energy of the object ,

Δ$K$ is the kinetic enegy change of the object.

$W_{net}$ = $K$ - $K_{0}$ = Δ$K$.
