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 ...

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 ...

“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 ...

We are talking about Centrifugal and Centripetal forces using a tornado as an example. Centripetal force is a force that keeps an object moving in a circular path, this force points TOWARDthe center ...

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 ...

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 ...
