Freefall and free fall are terms used to describe the trajectory of an object without propulsion and not experiencing air friction, e.g. a satellite in orbit around a gravitational source, such as the Moon's trajectory around the planet Earth, or the Earth's orbit around the Sun.

More generally, the condition "not experiencing air friction" is dropped: in parachuting, freefall (skydiving) refers to the act of falling and delaying the opening of a parachute.

Freefall is also the title of a popular Web-based comic strip written and drawn by Mark Stanley. It is a humorous science fiction story cataloguing the misadventures of the starship Savage Chicken and its crew: Sam, a lovable two-timing con artist; Helix, a childlike robot; and Florence, a genetically engineered "Bowman's Wolf" (DOGGY!).
