==Air Resistance==
Short Description of Topic
In real life there are a lot factors that affect motion. When first learn physics it is much simpler to calculate the motion of an object if forces such as drag and friction are taken out of the equation because it simply makes understanding motion much easier. In this section we will be exploring the concept of air resistance in motion.

Air resistance is a force that essentially opposes motion and dissipates energy. Much like other opposing forces, air resistance is dependent on both the speed and the size of the surface area of the object. Many things go into what affects the force of air resistance, and it can be defined by the following equation:

What are the mathematical equations that allow us to model this topic.  For example <math>{\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net}</math> where '''p''' is the momentum of the system and '''F''' is the net force from the surroundings.
C_D = drag coefficient (typically between .3 and 1.0)
A = cross-sectional area
v = speed of object

Air resistance is affected by speed because it increases as velocity increases. This can be seen because there is always gravitational force acting on the object downward, but as the speed increases the air resistance increase making the net downward force much much smaller until it becomes 0. This means that at some point the object reaches terminal speed because there is no longer a net force acting upon it.
