This video explains the role of normal force in forces of constraint, shedding light on how it affects the motion of objects ...

I can't help myself. I have to say something about this awesome water slide as seen on io9. You really should check out the io9 article - an interesting read. But for me, let me see if I can estimate ...

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 ...

The force exerted on a charge is always perpendicular to the velocity of the charge. The force exerted changes the velocity so the direction of the applied force changes as a result. Overall this ...
