Principle of Conservation of momentum

providing no external forces act the total momentum before a collision is equal to the total momentum after a collision measured in the same direction

7 of 21

Elastic collision

kinetic energy is conserved as well as momentum

8 of 21

Newton's Second Law

The rate of change of momentum is proportional to the resultant force acting on it and takes place in the same direction as the force

9 of 21

Impulse

The product of the force and the time for which it acts- and hence impulse is the change in momentum of the object on which the force acts. Equal to the area under a force-time graph.

Cetripetal force

produces centripetal acceleration and acts towards the centre of the circle

11 of 21

Simple harmonic motion

an oscillation in which the acceleration of an object is directly proportional to its displacement from the midpoint and is directly towards the midpoint.

Newton's Law of gravitation

Every particle of matter attracts every other particle of matter with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

13 of 21

Gravitational field strength, g

gravitational force exerted on a unit mass placed at a certain point in the field (NKg-1)

14 of 21

Gravitational potential V

the work done in moving a unit mass from infinity to that point, area under a force-distance graph gives the work done

15 of 21

Kepler's law

T squared= 4pi squared x distance cubed divided by GM

16 of 21

Coulombs Law

The force acting between two charges is proportional to the product of the charges and inversely proportional to the square of their separation.

17 of 21

Electric field strength

the force acting on a unit of positive charge placed at a certain point in the field (NC-1)

18 of 21

Electric potential

the work done us moving a unit positive charge from infinity to a certain point- scalar

19 of 21

Faraday's Law

the induced emf is directly proportional to the rate of change of flux linkage

20 of 21

Lenz's Law

The induced emf is always in such a direction as to oppose the change that caused it
