WebAug 27, 2016 · Long story short, energy and momentum will change if there's an applied force acting over a distance, even if the force is constant. The difference between kinetic energy and force may become more clear if you consider the difference between what's happening right now, versus over time. WebMar 25, 2024 · Among other differences, force is a vector (has a direction) while energy is a scalar (does not have a direction). Force is a push or a pull.

Force, Work and Energy - Types, Principle and Solved Questions
WebEither way, you do the same amount of work because you apply the same force (equal to your weight) through the same distance (the height of the stairs.) Power is work per time. That is, if you do the same amount of work in a shorter time, it takes more power. WebNov 5, 2024 · The work done by those two forces is given by: W1 = − ΔU1 W2 = − ΔU2 where U1 and U2 are the changes in potential energy associated with forces →F1 and →F2, respectively. We can re-arrange the Work-Energy Theorem as follows 1: Wnet = WC + WNC = − ΔU1 − ΔU2 + WNC = ΔK ∴ WNC = ΔU1 + ΔU2 + ΔK That is, the work done by non ... WebForce is perpendicular to the motion so the work done is zero. Describe a situation in which a force is exerted for a long time but does no work. Explain. W= F*d Work depends on 3 things: displacement, force and angle between force and displacement. If the displacement is 0 then the work done is 0. t pain what\u0027s your name
