An Investigation of a Model for Air Resistance
... Introduction: When an object falls near the Earth’s surface it experiences the force of gravity as well as a drag force due to air resistance. In first year physics, most students are told to “ignore” wind resistance. This lab is designed to show that a model equation may be tested. One of the simpl ...
