The reason airplane flights take longer when traveling west is because of the different speeds of rotation on Earth. The rotational velocity of Earth decreases as one goes from the Equator to the poles. This means that a place on the...

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:<b<br/>r/>

Va = Vb + Vrel + Vp/b

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...

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 veloc

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!

This nugget explains about the relative velocity with some special cases.

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...

Since the first curling rock curved around the first guard, there have been questions about the strange physics that give the game its name. Why exactly does a curling rock curl, instead of sliding in a straight line? The CBC’s “Physics...
