Laws of Motion

Isaac Newton's three basic laws of motion are presented here along with the equations that derive from them.

Conservation of Momentum :
An object in motions tends to remain in motion. An object at rest tends to remain at rest. An external force is required to change the momentum.
Relationship of Force, Mass and Acceleration : F = ma. Acceleration and force are vectors, and the force vector operates in the same direction as the acceleration.
Action / Reaction : For every action there is an equal and opposite reaction.

- RF Cafe

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
