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 ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).
