Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Finally, there is the kinetic frictional force (F K). This force depends on two things: the magnitude of the normal force and a coefficient of friction that is set for the two materials that are ...

There are two main types of friction: static and kinetic, according to the journal The Physics Teacher. Static friction operates between two surfaces that aren't moving relative to each other ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

As a result of the work done by this friction, the kinetic energy of the disk decreases. This is shown in the initial stage of the animation shown below. As the disk continues to roll with slipping, ...

Ignoring the friction between the balls and the table or any spin imparted to the cue ball, ideally the total kinetic energy of the two balls after the collision is equal to the kinetic energy of ...
