Lab#4 Modeling the fall of an object falling with air resistance

Part 1: Determining the relationship between air resistance force and speed

Purpose: 
    To observe the effect of air resistance on falling coffee filters and in determining how the terminal velocity of a falling object is affected by air resistance and mass, choose which of the two force models best represents the air resistance effect on the falling coffee filters.

Part 2: Modeling the fall of an object including air resistance

    When falling, there are two forces acting on an object: the weight, mg, and air resistance. In the real world, because of air resistance, objects do not fall indefinitely with constant acceleration. At terminal velocity, the downward force is equal to the upward force, so depending on whether the drag force follows the first or second relationship.
