air resistance example

initial velocity of object when it is released

0 m/s

force of friction when the object is initially released

0 N

What happens when the object falls

velocity is down but force of friction is up

what happens to magnitude of net force when the object falls

magnitude decreases

what happens to the force of friction and velocity as the object falls

force of friction increases and velocity increases

what happens to acceleration since net force is decreasing

acceleration decreases

since net force and acceleration are down

speed increases but the rate it increases gets smaller

what happens if the object falls far enough

the magnitude of force of friction becomes equal to weight

when force of friction and weight are equal

net force is 0

when the object falls far enough and net force is zero

acceleration is 0, velocity is constant and down, velocity is known as terminal velocity
