Slows an object down or speeds one up.
terminal velocity is the final maximum velocity of a falling object.
The object opposes the air and while falling of the object the initial velocity will become zero , and the final velocity will have some value's this is how air will resist the velocity of falling object ...........
Air resistance causes friction and slows an object.
When dropped the mass of an object does not affect the rate at which it falls. The size and shape may affect the wind resistance which affects falling velocity but heavier objects will not fall faster than lighter objects with all other variables constant.
Resistance (newtons) = velocity( in m/s)2 * drag coefficient of the object
As objects fall, they are accelerated by the force of gravity, which causes them to continually fall faster, until they either reach the ground, or until they reach what is known as terminal velocity, which is the speed at which air resistance is equal to the force of gravity, so that the falling object does not accelerate any more.
Frontal surface area.
The object's velocity and cross sectional area.
It slows the acceleration - possibly down to zero @ "terminal velocity".
Objects when falling that cannot ignore air resistance are things like feathers, leaves, seeds, or small pieces of paper just to name a few. Objects when falling that can ignore air resistance are things such as objects that are heavy and compact like rocks or metal balls.
It reduces the acceleration of the falling object due to friction.
Without air resistance, there would be no such thing as terminal velocity.
