Free Fall
Motion under the influence of gravity only; acceleration a = g (assuming no air resistance).

Free fall motion
An object in free fall has acceleration a = g (downward). The equations of motion apply with a = g. If air resistance is negligible, all objects fall with the same acceleration regardless of mass.
✔ Key takeaway: Free fall: a = g; same equations as uniformly accelerated motion.

In a vacuum, would a feather and a hammer fall at the same rate?
