Hint
Answer
Any two point charges exert an electrostatic force on eachother that is directly proportional to the product of their charges and inversely proportional to the square of their separation
Coulomb's Law
The magnitude of the induced e.m.f. is directly proportional to the rate of change of magnetic flux linkage
Faraday's Law
The force applied is directly proportional to the extension of the spring, unless the limit of proportionality is exceeded
Hooke's Law
The recessional speed v of a galaxy is directly proportional to the distance d from Earth
Hubble's Law
The orbit of a planet is an ellipse, with the Sun at one of the two foci
Kepler's First Law of Planetary Motion
A line segment connecting the planet to the Sun sweeps out equal areas during equal intervals of time
Kepler's Second Law of Planetary Motion
The square of the orbital period T of a planet is directly proportional to the cube of its average distance r from the Sun
Kepler's Third Law of Planetary Motion
At any point in an electrical circuit, the sum of the currents into a point is equal to the sum of the currents out of a point; electrical charge is conserved
Kirchhoff's First Law
In a closed loop of an electrical circuit, the sum of the e.m.f.s is equal to the sum of the p.d.s
Kirchhoff's Second Law
Hint
Answer
The direction of the induced e.m.f. or current is always such to oppose the change producing it
Lenz's Law
A body will remain at rest or continue to move at a constant velocity unless acted upon by a resultant force
Newton's First Law
The rate of change of momentum of an object is directly proportional to the resultant force, and takes place in the direction of the force
Newton's Second Law
Who two objects interact, each exerts an equal but opposite force on the other during interaction
Newton's Third Law
The force between two point masses is directly proportional to the product of the masses and inversely proportional to the separation between them
Newton's Law of Gravitation
The potential difference across a conductor is directly proportional to the current in the conductor, so long as temperature remains constant
Ohm's Law
For a body in rotational equilibrium, the sum of the anti-clockwise moments is equal to the sum of the clockwise moments about the same point
Principle of Moments
The peak wavelength at which the intensity of radiation from a black body is a maximum and is inversely proportional to the absolute temperature T of the black body
