Boyle's Law
The volume of a fixed mass of gas is inversely proportional to pressure exerted on it , provided temperature remains constant.
1 of 10
Brownian motion
The random movement of small particles when suspended in a liquid or gas
2 of 10
Centripetal acceleration
a=v^2/r The acceleration of a body moving in a circle with constant speed acting towards the centre of the circle.
3 of 10
Conservation of momentum
Physical law stating that in the absence of external forces the total momentum remains constant
4 of 10
Gravitational field strength
The gravitational field strength at any point is the force acting per unit mass at that point
5 of 10
Gravitational force
Force due to a gravitational field acting on an objects mass
6 of 10
Inelastic collision
Momentum is conserved but KE is not
7 of 10
Keplers 3rd Law
The period of a planet orbiting the sun squared is proportional to the mean radius of its orbit cubed.
8 of 10
Newtons 1st Law
An object will remain at constant rest/uniform velocity unless acted upon by a force
9 of 10
Specific latent heat of fusion
The energy required to change the state of 1kg of a substance at its melting point from solid to liquid
