Newton's Laws of Motion

Confusing Version from Wikipedia...

First law
There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force." Newton's first law is often referred to as the law of inertia.

Second law
Observed from an inertial reference frame, the net force on a particle of constant mass is proportional to the time rate of change of its linear momentum: F = d(mv)/dt. This law is often stated as, "Force equals mass times acceleration (F = ma)": the net force on an object is equal to the mass of the object multiplied by its acceleration.

Third law
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence, "To every action there is an equal and opposite reaction."

Simplified version:

First Law:
Law of Inertia
A stationary object will not move unless an unbalanced force acts on it...

Second Law:
Law of Force, Mass and Acceleration
The acceleration of an object depends on its mass and the force applied on it...

Third Law:
Law of Action and Reaction
For every action, there is an equal and opposite reaction...

Here's a video from youtube using animation to demonstate Newton's laws...Hope it helps... :D


There's also songs about Newton's Laws on youtube...I wanted to post one here but the embeded code had a problem so here's the link:

That's about it:P
