Equations for work done

WebThe quantity 1 2 mv 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the translational kinetic energy, KE = 1 2 mv 2, 7.12. WebThe negative of negative work refers to the numerical value that results when values of F, d and theta are substituted into the work equation. Since the force vector is directly opposite the displacement vector, theta is 180 …

Calculating the Amount of Work Done by Forces - Physics Classroom

WebThis is useful when one for instance want to calculate the work done on an object moving from point A to point B through the force field. W = ∫ F · d r along C, where C is the path of the object from A to B.

WebMar 26, 2016 · In physics, one major player in the linear-force game is work; in equation form, work equals force times distance, or W = Fs. Work has a rotational analog. To relate a linear force acting for a certain distance with the idea of rotational work, you relate force to torque (its angular equivalent) and distance to angle. WebDec 21, 2024 · The work equation (or the work definition, if you will) is: W = F \times d W = F × d where, W W — Work done; F F — Force applied to the object; and d d — Distance about which you moved the object. The force can be decomposed like this: F - m\times a F − m × a where, m m — Mass of the object; and
