- Momentum, impulse and collisions Momentum = mv (N s). Impulse = force × time = change in momentum.
- Moments and centres of mass Moment = force × perpendicular distance. For a rigid body in equilibrium: resultant force zero and total moment about any point zero.
- Circular motion and simple harmonic motion Angular speed ω; v = rω; acceleration towards the centre = v²/r = rω².
