Kepler's first law:
Planet orbits are ellipses with the sun at one focus of the ellipse.
Kepler's second law:
A line joining a planet to the sun sweeps out equal areas in the ellipse over equal times.
Kepler's third law:
The square of the orbital period of a planet equals the cube of its semi-major axis.
Newton's first law
An object at rest stays at rest. An object in motion stays in motion at a constant speed in a straight line unless acted upon by an unbalanced force.
Newton's second law
The net force on an object is equivalent to the product of object's mass and its acceleration
Newton's third law
Forces come in pairs. For every force, there exists and equal and opposite force.
