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: ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Units of measurement are are used to represent physical quantities like length, weight and other values. Units can be imperial or metric and can be converted by conversion factors. The movement of ...

Hydraulics is great for lifting heavy loads and applying large amounts of force, but the same power that is required to exert a large amount of lifting or compression force can also do damage or ...
