If the force is constant F F and the object it is exerted on is moved by a distance Δx Δ x, then W = FΔx W = F Δ x. If the force is not constant but a function of the position, this turns into an integral: W =∫x2 x1 F(x)dx. W = ∫ x 1 x 2 F (x) d x.

Let’s examine how doing work on an object changes the object’s energy. If we apply force to lift a rock off the ground, we increase the rock’s potential energy, PE. If we drop the rock, the force of gravity increases the rock’s kinetic energy as the rock moves downward until it hits the ground.
The rate of doing work is equal to the rate of using energy since the force transfers one unit of energy when it does one unit of work. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts.
The work done by the force may also be converted to kinetic energy or potential energy of the object. When work is converted to different forms of energy you can: use the work done...
29 lis 2022 · We can apply force to change the energy quantity of system. For example, we apply force to body, and give it kinetic energy. We apply force to gas in piston and we increase its temperature or also increase kinetic energy of molecules.
