Explore how quadratic drag influences the motion of objects moving in a straight line. In this video, we break down the physics behind resistive forces that increase with the square of velocity, ...

Explore the dynamics of circular motion with **“Understanding Tension In Two Masses Moving In A Vertical Circle.”** This physics tutorial breaks down the concept of tension forces acting on two masses ...

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 ...

The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves cycles of sticking and sliding between two surfaces. But that model is best ...

Tiny, repeating detachments between sole and floor — thousands of times a second — create the distinctive squeak heard on the ...
