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.

If you know the two position vectors, then the displacement vector would be: Finally, we are ready for the definition of average velocity. When the object goes from position 1 to 2, it will take ...

The red arrow shows the direction of the angular velocity vector. Now for my next definition. Twist: A human rotation about an axis that runs the length of the body. Again, here is an animation ...
