This equation is called the continuity equation for steady ... A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a ...

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.

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed ... In addition to the blue swept areas, the green velocity vector is ...
