How does work relate to kinetic energy?

1 Answer

Answer:

Refer to explanation

Explanation:

The kinetic energy ( KE ) of an object of mass m that is moving with velocity v is

#KE=1/2*m*v^2# where m=mass of the object and #v# its speed.

The work done on an object by a force equals the change in kinetic energy of the object hence

#W=KE_(f)-KE_(i)=1/2*m*(v^2-v_o^2)#

where #KE_f#=final kinetic energy and #KE_i#-initial kinetic energy
