Relative Motion with rotating reference axes Example (part 1)
To solve for the velocity of a point A moving relative to an object that is rotating then we can use the relative velocity (for rotating reference frames) equation: Va = Vb + Vrel + Vp/b

Relative motion (with rotating axes) Summary
The equations for NON rotating reference axes are: Va = Vb + Va/b and a_a = a_b + a_a/b But these equations are only true if the relative axes are not rotating. If the relative frame of reference xy is rotating (eg think of a policeman...

Relative velocity (with rotating axes) Proof
If the relative axes xy aren't rotating (w = 0) then the velocity equation becomes Va = Vb + Va/b However, in general, relative reference axes can rotate and the following relative velocity equation becomes Va = Vb + Vrel + Vp/b Note...

Special Relativity Part 3: Length Contraction
Time dilation was pretty weird, huh? Well we aren't done yet! Time is relative, and so is space! Different observers measure different lengths for objects and journeys. Weird stuff!

Physics Kinematics: Motion in a Straight Line - Relative Velocity in 1D
A massive sinkhole appears in the middle of Central Park! Which superhero will be the first to respond? This lesson will explain how to calculate the relative velocity of an object in different inertial frames of reference. Definitions...
