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 ...

Ask someone to list the greatest inventions and discoveries of all time, and they are likely to come up with such things as fire, the wheel, electricity, and perhaps penicillin. In my mind, however, ...

Design and kinematic analysis of mechanisms. Course topics include linkage synthesis and motion analysis (position, velocity and acceleration), cam, gear and power train design, and technical ...

The diagram shows what happens to the speed of a skydiver from when they leave the aircraft, to when they reach the ground after their parachute opens. Before the parachute opens: Immediately on ...
