* Gravity is a fundamental force: Gravity is a force of attraction between any two objects with mass. It's constant and doesn't change based on things like air resistance.
* Drag is a force of resistance: Drag is a force that opposes the motion of an object through a fluid (like air or water). It arises from friction and pressure differences.
How drag indirectly affects the *apparent* force of gravity:
While drag doesn't directly change gravity, it can affect the *apparent* force of gravity in some situations:
* Terminal velocity: When an object falls through the air, drag increases with speed. Eventually, the drag force equals the gravitational force, and the object stops accelerating. This is called terminal velocity. In this case, the object appears to be "floating" due to the balance between gravity and drag, but gravity is still acting on it.
* Parachutes: Parachutes significantly increase drag, slowing the descent of a skydiver. This makes the apparent force of gravity much less, giving the impression of a gentler descent.
Key Point: Drag doesn't change the actual force of gravity, but it can oppose the motion caused by gravity, leading to a perceived change in its effect.
