Why Don't Birds Have Vertical Tails Like Airplanes?
How do you tell a plane from a bird? The vertical tail, of course! By why can birds fly without a vertical tail, and how do planes use their vertical tails to stay in the air?

Why We've Only Ever Seen the Sun's Poles Once
The Ulysses mission revolutionized our understanding of the sun, but it's been the only orbiter to take this kind of out-of-ecliptic journey. Will an upcoming mission give us even more?

Wavelength
In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

Wave Energy
In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

Friction: Crash Course Physics
Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction!...

Torque
In this video Paul Andersen begins by discriminating between translation and rotational motion. He then explains how a torque is the product of the lever arm and the force perpendicular. The lever arm must be perpendicular to the axis of...

Transverse and Longitudinal Waves
In this video Paul Andersen compares and contrasts transverse and longitudinal waves. Waves carry energy through oscillations. In transverse waves the oscillations are perpendicular to the direction of the wave and in longitudinal they...
