WebbThis is known as Work-Energy Theorem. It can be represented as: K f – K i = W Where K f = Final kinetic energy K i = Initial kinetic energy W = net work done So the above equation follows the law of conservation of energy … WebbThe work-energy theorem for a rigid body rotating around a fixed axis is WAB = KB − KA 10.29 where K = 1 2Iω2 and the rotational work done by a net force rotating a body from point A to point B is WAB = θB ∫θA(∑ i τi)dθ. 10.30 We give a strategy for using this equation when analyzing rotational motion.

WebbWork-energy theorem. The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done. WebbWe learned the work-energy theorem, which is basically saying that when you do positive work on a body, you add that much kinetic energy to the body, and if you do negative … WebbWork. refers to an activity involving a force and movement in the directon of the force. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy. is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work. morries exotic cars
