|
|
Second Law
|
the orbit of a planet sweeps out equal areas in equal time intervals
|
|
|
Third Law

Newton's First Law
|
an object at rest or in uniform motion continues in that state unless acted on by an outside force; also called the Law of Inertia
|
|
|
Newton's Second Law
|
- the acceleration of an object is equal to the force applied divided its mass; Acceleration = force/mass
|
|
|
Newton's third law
|
- equal and opposite reaction force; bike with the compressed air
• Conservation of momentum - momentum, mass times velocity, is always conserved in a system unless acted upon by an outside force |
