Up to this point we have learned Kinematics and Newton's Laws. Let 's see what happens when we apply BOTH to our new formula for WORK!
We will start by applying Newton's second law!
Using Kinematic #3!
An interesting term appears called KINETIC ENERGY or the ENERGY OF MOTION!
The Work Energy Theorem
And so what we really have is called the WORK-ENERGY THEOREM. It basically means that if we impart work to an object it will undergo a CHANGE in speed and thus a change in KINETIC ENERGY. Since both WORK and KINETIC ENERGY are expressed in JOULES, they are EQUIVALENT TERMS!
" The net WORK done on an object is equal to the change in kinetic energy of the object."
