Impulse Impulsive force Action and reaction Newton’s Third Law of Motion

Principle of Conservation of Momentum

Momentum m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2 Collision and explosion Force • Gravitational field strength • Weight Newton’s Second Law of Motion

Force and Motion I

• displacement-time • velocity-time • acceleration-time Interpret type of motion Convert and sketch displacement-time graph into velocity-time graph and velocity-time graph into acceleration-time graph and Value of gravitational acceleration Inertia and mass Newton’s First Law

Linear motion Type of motion • At rest • Uniform velocity • Non-uniform velocity Distance and displacement Speed and velocity • Acceleration Linear motion equations v = u + at v 2 = u 2 + 2as 1 s = —(u + v)t 2 1 s = ut + —at 2 2 http://bt.sasbadi.com/p4072
