A level physics laws
Newton’s law of gravitation - force proportional to product of masses and inversely proportional to
square of separation B1 idea of force between point masses
Faraday’s law of electromagnetic induction - (induced) e.m.f. proportional to rate of change of
(magnetic) flux linkage
Coulomb’s law - force proportional to product of (two) charges and inversely proportional to square
of separation M1 reference to point charges
Law of thermodynamics
Newton’s first law of motion – an object remains at rest or in state if uniform velocity unless
it is acted on by a resultant force
Newton’s second law of motion – the resultant force of a body is proportional to the rate of
change of momentum of the body
Newton’s third law of motion Lenz law – An induced e.m.f is in a direction so as to produce effects that oppose the change
producing it
