Newtons first law
All objects will continue to be stationary or move with constant velocity unless acted on by an unbalanced resultant force
1 of 8
Newtons second law of motion
The rate of change of momentum is directly proportional to the resultant force acting on it
2 of 8
Newtons third law
When body A exerts a force on body B, body B exerts an equal and opposite force on body A
3 of 8
Linear momentum
The product of mass and velocity
4 of 8
Net Force (on a body)
Is equal to rate of change of it's momentum
5 of 8
Impulse
Product of force acting on a body and the time it acts for (also =to area under f/t graph)
6 of 8
Perfectly elastic collision
Collision where no momentum or KE is lost
7 of 8
Inelastic collision
momentum is conserved nut KE is not
