Newton’s Laws of Motion

Are Newton’s Laws True?

Where Did Newton Go Wrong?

Maxwell’s Electromagnetic Theory - 1873 James Clerk Maxwell (1831-1879)

The Michelson-Morley Experiment - 1887

Einstein’s Postulates of the Special Theory of Relativity

What is an Inertial Frame?

Where Did Einstein’s Postulates Come From?

Postulate #1 0.5 c

Postulate #2 0.5 c c

How Is This Possible? 0.5 c c

Consequence #1 Time Dilation (Part 1)

Consequence #1 Time Dilation (Part 2)

Consequence #2 Length Contraction (Part 1)

Consequence #2 Length Contraction (Part 2) v = 0 0.5 c 0.8 c 0.95 c

Are There Real Values for Time and Length?

Special Relativity Applied to Electric and Magnetic Fields

Special Relativity Applied to Electric and Magnetic Fields

Special Relativity Applied to Electric and Magnetic Fields

Einstein’s Corrections to Newtonian Mechanics

Einstein’s Corrections to Newtonian Mechanics

If “F = m a” isn’t true, why do we still use it?

What’s so “special” about Special Relativity?
