Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges ...

A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster ...

Students will apply their knowledge of physical science concepts to create a lunar lander game using Scratch. They will use Vernier force and acceleration sensors to understand forces and integrate ...

Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are ...

A roundtable that will meet quarterly to (1) consider challenges and opportunities associated with the Department of the Air Force’s (DAF) science and technology (S&T) mission requirements and the ...

There are many situations in which it's important to know how much force one object is applying to another item. A small, thin sticker has been designed to measure and relay such data, without ...

“I am one with the Force, the Force is with me.” In an hour, we will take on some of the science behind the movies – experimenting with forces and motion, using angles of incidence and refraction to ...

Chalmers researchers have developed a simple, light-based platform to study the mysterious “invisible glue” that binds materials at the nanoscale. Gold flakes floating in salt water reveal how quantum ...
