Newton's Second Law provides the formula...
F=ma
F1=F2
a=F/m
m=F/a
2
An object on the ground or on a surface must overcome this force in order to start its motion.
Air Resistance
Applied
Gravity
Friction
3

Elephant
Both are the same
Feather
Neither one accelerates
4
Terminal Velocity (the point when the object reaches it's highest velocity) occurs when....
Air Resistance(F-air) balances out the force of gravity
When acceleration increases
At the peak height
5
What is Net Force?
Force divided by Time
