Study Notes

Free Fall in General Relativity

Free fall in the context of general relativity is the motion of an object under the sole influence of gravity, without any other forces acting on it.

Conditions for Free Fall

An object is considered in free fall when it is under the sole influence of gravity, with no other forces acting on it.

Examples of Free Fall

An object dropped from rest in a uniform gravitational field, such as an object dropped from the surface of the Earth, is an example of an object in free fall.

Weightlessness in Free Fall

When a body is in free fall and there are no other forces acting on it, the sensation of weight is zero, as the body is accelerating downward at the same rate as the gravitational force.

Moon's Motion around the Earth

The Moon's motion around the Earth is an example of a orbit, which is a stable trajectory that is influenced by the gravitational force of the Earth, but not in free fall.
