The speed of an object does not require a direction to be considered, it simply has a value and unit, for example, 27 \(m\,s^{-1}\). Velocity is a vector quantity which requires a value, unit and ...

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.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: Estimation of position, velocity, and attitude of a rigid body is crucial for various applications. Many of these rely on position and Magnetic, Angular Rate, and Gravity (MARG) sensors, ...
