Kinetic energy is the energy possessed by an object due to its motion. It depends on both mass and the square of velocity — doubling speed quadruples kinetic energy, while doubling mass only doubles it. KE is the work-energy theorem in action: the net work done on an object equals the change in its kinetic energy.

Przewodnik krok po kroku
- 1KE = ½mv² (joules, J)
- 2m = mass in kg, v = velocity in m/s
- 3Momentum p = mv (kg⋅m/s) — conserved in collisions
- 4Work done to bring to rest = KE (e.g. braking distance calculation)
- 5KE is scalar (no direction); momentum is a vector
