Web6 de jun. de 2024 · The kinetic energy is indeed the work you have done (assuming no change in potential energy), however this is also neglecting the effect of friction. In real life, the kinetic energy of the box is going to be constant if its moving at a constant velocity even if you are exerting a force on the box and hence doing work on the box.

WebThe concept of force is closely related to energy: force can be seen as something which changes the energy of a system by doing work on the latter. In kinematics, work is defined by a spatial integral over the force acting on an object: W = ∫ F → ⋅ d x →. Force is defined as a change in a particle's momentum. Web2 de nov. de 2010 · I believe this is similar to the difference between "mechanical energy" and "work" (where "work" refers to the transfer of such energy). However, the two terms are actually often used interchangeably. WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent … barny perraton
