Whenever two bodies interact, the forces they exert on each other are equal and opposite 1 of 9 What is Newton's Third Law principle? All forces arise in pairs and force pairs are of the same type 2 of 9 What is centripetal force? The resultant perpendicular force towards the centre of the circle required to keep a body in uniform circular motion 3 of 9 Equation for momentum mass x velocity 4 of 9 Equation - momentum (Newton's second law) force (newton, N) = change in momentum (kilogram metre per second, kg m/s) ÷ time (second, s) 5 of 9 What is elastic collision (Momentum) collide and move in opposite direction 6 of 9 What is inelastic collision (Momentum) collide and move in same direction 7 of 9 Conservation of momentum The total momentum before a collision = The total momentum after a collision 8 of 9 What is inertia? an object's resistance to a change in motion 9 of 9
