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 ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on ...

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 ...

We've performed experiments that have tested the gravitational force law down to micron-sized scales, and on astrophysical scales in extreme environments, such as the galactic center, merging ...

While many theories within quantum mechanics are not universally agreed upon or understood, it's a powerful branch of physics.

Approximately 43 percent of Apollo, Skylab, Soyuz/Salyut and Shuttle crewmen have experienced symptoms resembling motion sickness during their first several days in space. This paper reviews the the ...
