Ford showed off an all-electric F-150 pickup truck towing a freight train full of more F-150s. The stunt relies heavily on one force to work: friction.

There are quite a few physics textbooks that actually ask about work done by friction. The first book I grabbed had an example that was something like this: Jake pulls a box with a mass of 22 kg.

Crash Course Physics is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart ...

The story takes place in an area of physics that has been long-neglected: friction. Everyone knows it exists, engineers have a bunch of empirical formulas to calculate it, but no one gave much ...

IIT Kanpur assistant professor Adhip Agarwala explains the physics of friction, its effects on various aspects of daily life in India, and how it can be reduced or eliminated.

The friction of the spindle against the hearth board creates heat – kind of like how your hands warm up when you rub them together. As the spindle continues to spin, it grinds away the charred wood to ...

New law of physics helps humans and robots grasp the friction of touch Date: April 29, 2021 Source: North Carolina State University Summary: Although robotic devices are used in everything from ...

Friction at the atomic scale appears to depend on the speed at which two surfaces move past each other. This surprising behaviour was observed as the tip of an atomic force microscope (AFM) moves ...

Understanding the physics of fire by friction and the different variables involved can make a big difference and help the fire start more quickly with less effort. First, keep it small.
