What is Kepler's Third Law of Planetary Motion?
A planet orbits a star in an elliptical shape
Segment between Sun and Planet has same area in same time
Planet's orbit is an ellipse with the Sun at one of two foci
T2 ∝ r3
3
What is Newton's Third Law?
Two objects interact and exert opposite and equal forces
Two objects interact and exert equal forces on eachother
Rate of change of momentum ∝ Resultant force
A body will remain at rest unless a resultant force acts
4
What is Newton's First Law?
Body will remain at rest unless acted upon by a net force
Two objects interact, each exerts an equal force
Rate of change of momentum ∝ Resultant Force
Two objects interact each exerts an equal yet opposite force
5
What is Boyle's Law?
P ∝ 1/V
P ∝ V provided mass and temperature don't vary
P ∝ V
P ∝ 1/V provided mass and temperature don't vary
6
What is Kirchoff's Second Law?
Sum of e.m.f's = Sum of p.d's in a closed circuit
Current in = Current out
Sum of e.m.f's = Sum of p.d's
Sum of Current in = Sum of Current out
7
What is Wien's displaement law?
λ ∝ 1/T
λmax ∝ 1/T
λ ∝ 1/T
λmax ∝ T
8
What is Hooke's Law?
F = k/x
F = kx
F ∝ 1/x
F ∝ x
9
What is Archimedes Principle?
Upthrust is equal to volume of liquid displaced
Force on an object in liquid is equal to its weight
Upthrust on an object is equal to weight of fluid displaced
Upthrust is proportional to weight of fluid displaced

13
What is Lenz's Law?
Direction of induced e.m.f is the same as the change
Direction of induced current is always opposite tothe change
Direction of induced e.m.f is always opposite to the change
Direction of induced current is the same as the change
14
What is Newton's Second Law?
Rate of change of momentum ∝ Resultant force
Two objects interact and exert equal forces on eachother
Two objects interact and exert opposite and equal forces
A body will remain at rest unless a resultant force acts
15
What is Kirchoff's First Law?
Sum of Current in = Sum of Current out, at any point
Sum of e.m.f's = Sum of p.d's in a closed circuit
Current in = Current out, at a certain point
