A body will remain at rest or continue to move with constant velocity unless acted upon by a force
1 of 17
Newton's Second Law
Force is proportional to the rate of change of momentum
2 of 17
Newton's Third Law
When one body exerts a force on another, the other body must exert an equal in magnitude but opposite in direction force on the first body
3 of 17
Newton's Law of Gravitation
The gravitation force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of separation
4 of 17
The Newton
The force which gives a mass of 1kg an acceleration of 1ms-1
5 of 17
Impulse of a Force
Product of a force acting on a body and the time it is acting, equal to the rate of change of momentum
6 of 17
Principle of Conservation of Momentum
Total momentum is conserved for a closed system
7 of 17
Gravitational Field Strength
Force per unit mass
8 of 17
Circular Motion
When a net force acts on an object perpendicular to the velocity
9 of 17
Simple Harmonic Motion
Acceleration is directly proportional to the displacement and is in the opposite direction to the displacement
