How the formula works
W = F·d·cos(θ) | KE = ½mv² | PE = mgh | P = W ÷ t
- Work (W) = Force × Distance × cos(angle) — only the component of force along the motion does work
- Kinetic Energy (KE) = ½ × Mass × Velocity²
- Potential Energy (PE) = Mass × Gravity × Height
- Total Mechanical Energy = Kinetic Energy + Potential Energy
- Power (P) = Work ÷ Time — the rate at which work is done
