Equations for work done
WebThe work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product For example, if a force of 10 newtons ( F = 10 N) acts along a point that … WebAfter taking the dot product and integrating from an initial position y i to a final position y f, one finds the net work as. W net = W grav = − m g ( y f − y i), where y is positive up. The work-energy theorem says that this equals the change in kinetic energy: − m g ( y f − y i) = 1 2 m ( v f 2 − v i 2). Using a right triangle, we ...

WebWork done is measured in joules (which has symbol J). So if we have a constant force of magnitude F newtons, which moves a body a distance s (meters) along a flat surface, … WebThe equation used to calculate the work done is: work done = force × distance \ [W=F\times d\] This is when: work done (W) is measured in joules (J) force (F) is measured in newtons...
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
WebMay 20, 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 — … WebExample 1: Calculating the Work Done by a Force Acting on a Particle Where the Force and Position Are Given as Vectors. A particle moves in a plane in which ⃑ 𝑖 and ⃑ 𝑗 are perpendicular unit vectors. A force ⃑ 𝐹 = 9 ⃑ 𝑖 + ⃑ 𝑗 N acts on the particle. The particle moves from the origin to the point with position vector − 9 ⃑ 𝑖 + 6 ⃑ 𝑗 m.
