The detection of a moving object's velocity by the visual system is thought to require several sequential computational steps. Bradley and Goyal outline current theoretical models that explain how ...

How to Calculate How Fast a Plane’s Flying—While You’re on It When you look out of the window of a plane, everything looks so small. But they're all big enough to do some physics.

Discover how to calculate the modulus (magnitude) of a velocity vector! This tutorial explains how to find the speed of an object from its velocity components in both 2D and 3D motion. Perfect for ...
