Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
the function of air resistance
A
slow down something
B
speed things up
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Q: Why does air resistance slow things down? With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.

Detailed explanation-2: -By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.

Detailed explanation-3: -As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile. The effect of air resistance is very small, but needs to be considered if you want to increase the horizontal component of a projectile.
