Einstein's general theory of relativity expanded on the special theory, explained gravity, and predicted phenomena such as black holes and the expanding universe.

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.

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

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.

Acceleration is a fundamental quantity needed to understand the physics of motion. It has a precise meaning different from everyday use.

When Albert Einstein first realized that gravitational mass and inertial mass were the same thing, the resulting thoughts led him to expanding the theory of relativity.
