Energy an object possesses due to its motion
Stored energy due to forces between objects in a system
Ek=12mv2E_k = \frac{1}{2}mv^2Ek=21mv2
Ug=mghU_g = mghUg=mgh
Joule (J), equal to kg⋅m2⋅s−2\text{kg} \cdot \text{m}^2 \cdot \text{s}^{-2}kg⋅m2⋅s−2
Scalar (has magnitude only, no direction)
Energy cannot be created or destroyed, only transformed
W=F∥s=FscosθW = F_{\parallel}s = Fs\cos\thetaW=F∥s=Fscosθ
Wnet=ΔEkW_{\text{net}} = \Delta E_kWnet=ΔEk (net work = change in KE)
Kinetic energy + gravitational potential energy
