Is energy equal to work

WebTo prove that Kinetic Energy is ½ mv^2 We already know that Energy w = f x s that is force x displacement. So, ΔK = W = FΔs = maΔs From the third equation of motion that is v^2 - u^2 = 2aΔs (-1) where v = final velocity, u = initial velocity, a = acceleration, and Δs denotes change in displacement ΔK = maΔs, so from equation (1) WebSep 17, 2024 · The work function is the attainable energy needed to detach electrons from the metal surface. So, the maximum energy EK of the photoelectron will be equal to the energy of the incident photon (hf) minus the work function (), because an electron has to do some work to escape the potential from the metallic surface.

WebWork done = 10 × 2 = 20 J The triangle above will help you to rearrange the equation. Work done has the same units as energy - joules. This is because energy is the ability to do work.... WebFeb 17, 2024 · The work-energy theorem states that work is equal to the change in the kinetic energy of an object. So, work is equal to the final value of the kinetic energy minus the initial value of the kinetic energy: \(W=∆KE-KE_{f}-KE_{i}\). It is also important to note that work can be either positive or negative. For example, if you are pushing a box ... chlorine cl- is what type of ion https://sunnydazerentals.com
