A free falling object is an object which is falling under the sole influence of gravity - "In a state of free fall"

-On earth, free falling objects accelerate downwards at 9.8m/s
-Objects encounter air resistace
-Terminal velocity- the velocity at which a falling body moves through a medium

Air resistance will slow down the objects acceleration. As the object falls faster, the air resistance increases until it equals the force of gravity. The object has reached its terminal velocity.


Definitions:
-Force- A push or pull working on an object
-Acceleration-The rate at which an object increases speed
-Gravity-The force working on objects that pulls them toward each other



Distance: is measured in (feet) meters (m)
Time: is measured in seconds (s)
Acceleration: is measured in meters per second (m/s)



Everyday Example: A tennis ball falling and hitting the ground



Sample Problem:

Sam fell off of a mountain on another planet. He fell 250 feet in 2.5 seconds.
What was his acceleration?
