Answer:
Work is equal to the change in kinetic energy.
Explanation:
Since energy cannot be created nor destroyed, and work is a form of energy, the work done by a force acting on an object must be equal to the kinetic energy gained by the object.
This is summarized by the work-energy theorem, which can be written as:
[tex]W=\Delta K = K_f - K_i = \frac{1}{2}mv^2 - \frac{1}{2}mu^2[/tex]
where
W is the work done on the object
m is the mass of the object
v is the final speed of the object
u is the initial speed of the object
