However, objects can develop a static net charge if they pick up extra electrons or lose some electrons. This can happen through friction. Objects with opposite net charges attract, and objects with ...

Statics is the study of objects when they're NOT accelerating. Whenever you walk across a bridge or lean on a building, Statics are at work. Statics is the study of objects when they're NOT ...

A century after Nikola Tesla sketched a turbine with no blades, researchers are now using that same counterintuitive design ...

Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car. Friction ...
