• Newton's Laws and Momentum
• Momentum
• ft = change in mv
• Car crashes and crumple zones
• p = mv
• kgms^-1
• Vector
• Conservation
• Explosions
• Collisions
• Inelastic
• Elastic
• Untitled
• Impulse
• ft = change in mv
• Car crashes and crumple zones
• Newton's Second Law
• Definition
• The Newton
• 1 N si the force that gives a mass of 1kg an acceleration of 1m/s^2
• F is proportional to the change of momentum / the change in time
• F = ma if m is constant
• w = mg
• Newton's Third Law
• Definition
• 'Action and reaction'
• Pairs of forces
• Equal magnitude, opposite direction, same type of force, acting on different bodies.
• Newton's First Law
• Definition
• Force causes acceleration
• Balanced forces
• No net force, no acceleration
