Centripetal vs. Centrifugal
Centripetal force and centrifugal force are related but often confused.

Centripetal Forces and Centrifugal Effects
Inward centripetal forces keep objects moving in circular paths. Outward centrifugal effects are not real forces. They are caused by an object's inertia.

Understanding Physics of Inertial Forces
Inertial forces are not really forces. They are effects that feel like forces but arise from Newton's inertial law in a reference frame that is accelerating.

Why Are Astronauts Weightless
There is a myth that there is no gravity in space, so astronauts are weightless. Orbiting astronauts are weightless because they are falling freely around the Earth.
