Study Notes
Free Fall
- Free fall occurs when an object is acted upon only by the force of gravity.
- In the context of general relativity, a body in free fall experiences weightlessness.
- For an object to be considered in free fall, it must be under the sole influence of gravity, with no external forces acting upon it.
- The Moon is in free fall around the Earth despite its orbit, because the only force acting upon it is the gravitational force of the Earth.
- In a roughly uniform gravitational field, the absence of other forces results in a state of free fall, where the object accelerates towards the center of the gravitational field.
