Newtons first law 
An object will remain at rest unless acted on by a net force 

Newtons second law 
The rate of change of momentum on a object is directly proportional to the net force applied to it F=ma (when m is constant) 

Newtons third law 
When a body A exerts a force on body B, body B exerts a force that is equal and opposite 

Law of inertia 
Amount of resistance to change velocity 

Momentum 
Mass x velocity 

Newton 
The force that will accelerate a mass of 1kg by 1ms^2 

Impulse (p) 
Change in momentum Area under force time graph=impulse 

Principle of conservation of momentum 
In any direction, in the absence of external forces the total momentum of a system remains constant 

Perfectly elastic collision 
No momentum or energy is lost 

Inelastic collision 
Momentum is conserved but energy isn't 

Frequency 
Number of oscillations/cycles per unit time 

Angular frequency 
2pi x frequency 

Specific latent heat of fusion 
The quantity of energy per unit mass required to change from a solid to a liquid at constant temp. 

Specific latent heat of vaporization 
The quantity of energy required to change from liquid to a gas at constant temp. 

Kinetic theory assumptions 
Large n. Molecules moving randomly Collisions are elastic Negligible grav. Forces No intermoleculer force Travel in straight lines 

Internal energy 
The sum of random distributions of kinetic and potential energies of all molecules in the body 

Ideal gas 
All internal energy is random kinetic energy 

0th law of thermodynamics 
If A and B are in thermal equilibrium with C then A is in thermal equilibrium with A 

Specific heat capacity 
The amount of thermal energy required to raise the temperature of a unit mass by a unit temp 

Boyles law 
The volume of a fixed mass of gas is inversely proportional to the pressure if temperature is constant 

Newtons law of gravitation 
Force is proportional to product of masses and inversely proportional to square of seperation
