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 ...

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 ...

The velocity time graphs give all three variables for motion–velocity which can be read off at any time. Area is displacement and gradient is acceleration. Next page ...

For example, a lasercutting system with 20-Hz position bandwidth moves a 100-kg load at a constant velocity of 10 mm/sec and maintains a smoothness of 1% at sampling rates greater than 50 Hz.
