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: ...

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 ...

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 ...

THE U.S. Air Force is many things: young men in airplanes, bases scattered around the earth, schools and radars and stocks of bombs. But it is also an army of scientific pioneers who push out the ...

What is a Surface Force Apparatus (SFA)? The Surface Force Apparatus (SFA) is a highly sensitive scientific instrument used to measure the forces between two surfaces at the nanoscale. It allows ...
