Newton's First Law
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
10 of 17
Inelastic Collision
Some loss of Kinetic Energy during a collision
11 of 17
Kilowatt-Hour
The energy used by 1kW device in an hour
12 of 17
Perfectly Elastic Collision
A collision with no loss of Kinetic Energy
13 of 17
Specific Heat Capacity
Energy required to change the temperature of 1kg of a substance by 1 degree C
14 of 17
Brownian Motion
Smoke particles move in random motion
15 of 17
Boyle's Law
Pressure is inversely proportional to the volume for a fixed mass of gas at a constant temperature
16 of 17
Internal Energy
The sum of the random distribution of kinetic and potential energies associated with the molecules of a system
