WebFeb 20, 2024 · This quantity is our first example of a form of energy. Work-Energy Theorem. The net work on a system equals the change in the quantity 1 2mv2. Wnet = 1 2mv2 − 1 2mv2 0. The quantity 1 2mv2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. WebThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is. Δ U = Q − W. 12.6. Here, Δ U is the change in internal energy, U, of the system.

WebThis is why there is no work done on the system if the applied force and the resultant displacement are perpendicular. But, that perpendicular force could affect the direction of motion of the body (since a force on a body should accelerate it somehow). So, no work is needed to change the direction of a body, even though it happens only by a force. WebQuestion: GPE-mgh l- can work be done on a system if there is no motion?
