Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

Atomic friction: tiny effect may never be measured. (Courtesy: Shutterstock/Dmitriy Rybin) An excited atom decaying in a vacuum experiences a force very similar to friction, according to calculations ...

Explore the fundamentals of motion with Exploring the Basics of Static and Kinetic Friction Forces in Physics. Learn how friction influences movement, the differences between static and kinetic ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

When I watch films, TV shows or sports I often find myself thinking about the physics of the situation. Here in North America, we’re approaching the end of ice hockey season. The main aim of this ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...
