Newton's Three Laws

Introduction to Newton's Three Laws

Newton's Three Laws, named after Sir Isaac Newton, who derived the laws, provide the basis for the study of Dynamics, and describe the fundamental laws of motion. These three laws will serve as a springboard for all other topics concerning dynamics.

Mathematically, the laws can be written as the following:

First Law: If F = 0 then a = 0 and v = constant
Second Law: F = ma
Third Law: F _AB = - F _BA

We will spend the nest three section of this SparkNote examining the ideas behind Newton's Three Laws, and explaining the derivation of their mathematical formulas.
