Define the work-kinetic energy theorem

Question

Define the theorem and write the associated quotation

Answer 1

actually, the work done on a body, W = (component of force in direction of motion)(distance)

 

                                                    = increase in Kinetic Energy + increase in Gravitational Potential Energy

Answer 2

The work done on a body by a resultant force is always equal to the change in the kinetic energy of the body

Answer 3

Isn't this an important concept that your textbook will have presented?
