WebWork energy theorem - It states that the work done by the net force acting on a body is equal to the changed produced in kinetic energy of the body. Let F be the variable force ∴ Work done by this variable force , W=∫ xx fF⋅dx where x i is the initial position and x f is final position. Also Kinetic energy of an object , K=21mv 2 dtdK=mv dtdv WebRead: The net work equals the mass of the object times the velocity of the object squared divided by two from velocity initial to velocity final. Which works out to be: ⇒W net = 1 2 mv f 2− 1 2 mv i 2 This is where the definition of Kinetic Energy comes from: Kinetic Energy is defined as 1 2 mv Therefore the net work equation is: ⇒W net ... how do i look passing the fashion bar

WebJan 9, 2024 · Work done by the force equals the change in kinetic energy of the center of mass. So W = Δ K c m = 1 2 m V c m 2 and here is their proof To derive the translational part, we start with the equation of motion for the center of mass F = M d 2 R d t 2 = M d V d t The work done when the center of mass is displaced by d R = V d t is WebWork-Energy Theorem Proof. The work-energy theorem is applicable when the force varies with position and in direction. It is also applicable when the path takes any shape. In this … how much market share does fedex have
