College's Evil Side

Here's an excerpt from my most recent assigned reading from my Philosophy of Science course called Understanding Science (SC220)...

"This is called the law of addition of velocities. The velocity observed from the stationary frame of reference (V) is the sum of the velocity of the moving frame of reference (V1) plus the movement of the object within it (V2). V = V1 + V2 The law of addition of velocities provides a means of transforming motion calculations from one reference frame to another. The Galilean principle of relativity explains how people in different frames of reference can have different observations and yet both be right. By a simple set of calculations, we can transform one set of observations into the other - thereby explaining both observations by the same physical laws."

SHOOT ME NOW!!!

:: No offense, Mr. Hardman, my high school math teacher... you were amazing, but I couldn't stand physics then, and I hate it even more now!!! ::

So, if I'm standing on some train tracks (V), and a train is approaching me at 30 mph (V1), and Jack Bauer is running across the roof of the train toward me at 15 mph (V2), then in relation to me, Jack is traveling at 45 mph.

But if you were standing 100 yards away from the train tracks (V), then the velocity of the train (V1) and Jack Bauer(V2) with respect to you (V) would vary depending on the angles at the moment when the measurement was taken.

This is fun.

Credo,

Just Remember:

1) V2 = V1 + at
2) d = (V1)t + 1/2at^2
3) (V2)^2 = (V1)^2 + 2ad
4) F = ma
5) You Can't Push on a Rope

From Mr. Hardman, your favorite old Math and Physics teacher.

PS - And Don't Forget that Delightful Physics Class Poetry:

"Mary had a little lambda, whose frequency was low; and everywhere thay Mary went, the Photons were sure to go."

At some point did you link to a video of a duck?
