NEWTON'S LAWS

posted on 9:41 AM, July 8, 2010
Isaac Newton, Isaac Newton
Isaac Newton had three laws.
Now we have them; if we use them
We can explain motion's cause.

Isaac's First Law, not his best law
Says things do what they know best.
If they're resting, they will stay there;
If they're moving, they won't rest.

Just a bit more on the First Law
That you really ought to know:
An outside force that's not canceled
Really changes the whole show.

Now let's talk about this net force
And just what that it can do:
It can change the object's speed
And or its direction too.

Alright, what's next? Law number two
One equation and you'll pass:
To get the acceleration
Take the net force over mass.

Last but not least, Newton's Third Third Law
Forces always come in pairs.
Always there are equal forces
Even for our cheeks and chairs.
