All objects fall at the same acceleration due to:
Air resistance
Friction
Gravity
The size of the air resistance depends on:
The surface area of the object
its speed
the height which the object is dropped
the temperature of the air
Terminal Speed is when:
The air resistance force and weight are balanced.
The person can't travel any faster.
The parachute can't slow you down any more.
Factors that affect falling:
mass
surface area
acceleration (due to gravity)
The actual object
The wind speed
The distance the object is falling
There is no air resistance on the moon because:
There is no air
There is no gravity.
There is not enough gravity.
