Newton's First Law of Motion

Sir Isaac Newton first presented his three laws of motion in the 'Principia Mathematica Philosophiae Naturalis' in 1686. His first law states that every object will remain at rest or in uniform motion ... Continue reading

The story of Isaac Newton discovering the laws of gravity by watching apples falling from a tree is probably just a myth. He did do his work on gravity while at a farm, but that is about as much as can be proven.

How Fast is Mach 1?

A Mach number is a common ratio unit of speed when one is talking about aircrafts. By definition, the Mach number is a ratio of the speed of a body (aircraft) to the speed of sound in the undisturbed ... Continue reading
