Overview
Free fall is the motion of an object where gravity is the only force acting upon it. In a vacuum, all objects fall at the same rate, regardless of mass.
💡
Pro Tips
Assumes zero initial velocity and no air resistance.
The acceleration due to gravity on Earth is approximately 9.81 m/s².
In reality, falling objects eventually reach 'terminal velocity' due to air drag.

Fun Facts
"A person falling from a plane has a terminal velocity of about 195 km/h (120 mph)."
"Galileo famously proved that objects of different masses fall at the same rate by dropping balls from the Leaning Tower of Pisa."
"On the Moon, a hammer and a feather fall at the same speed because there is no air."
