Air Resistance


-Terminal Velocity
.maximum velocity reached by a falling object


-No net force
.no acceleration
.constant velocity


-Falling wth air resistance
.heavier objects fall faster because they accelerate to higher speeds before reaching terminal velocity

-Larger Force gravity
.need larger force of air
.need higher speed
FORMULAS:
for finding the:
-force~F=ma
-mass~M=f/a
-acceleration~A=f/m
F=ma
Force=Newtons-kg x m/s [squared]
Mass=kilograms
Acceleration=m/s [squared] (9.8 m/s [squared])
