State Newton's second law
Force is proportional to the rate of change of momentum and takes place in the direction of that force
1 of 12
State Newton's third law
When one body exerts a force on another, the other body exerts an equal and opposite force on the first body
2 of 12
Define equilibrium of forces
Resultant force is zero
3 of 12
Define the kilowatt-hour
The energy used by a 1kW device in one hour
4 of 12
State Boyle's law
Pressure is inversely proportional to volume for a fixed mass of gas at constant temperature
5 of 12
State Newton's first law
A body will remain at rest or continue to move with constant velocity unless acted upon by a force
6 of 12
Define the Newton
The force which gives a mass of 1kg an acceleration of 1m/s/s
7 of 12
Define linear momentum
Mass X velocity
8 of 12
State Keplar's third law
The cub of the planet's distance from the sun is directly proportional to the square of the orbital period
9 of 12
Define the impulse of a force
Force X time for which the force acts
