Terminal Velocity Web Hunt.docx



Use the internet and your textbook to help you answer the following questions.Suggested Starting LocationsText pg. 64 factors affect the amount of air resistance an object experiences? Explain each one.How does the speed of an object affect air resistance? Be as specific as possible.Imagine hanging your arm out a car window at slow speeds versus fast speeds. Explain the different forces on your arm.Look-up “Terminal Velocity”What does it mean?What is the NET force acting on any object at terminal velocity? How do you know?Draw a series of Free Body Diagrams for an object dropped from rest (including air resistance) as time progresses. The last diagram should represent terminal velocity.Setup a velocity-time graph.Using a dashed line, sketch the velocity of an object in free fall.What is the slope of the line you drew? Why?Using a solid curve, sketch the velocity of an object falling with air resistance on the same graph.Mark terminal velocity on your sketchImagine that a baseball is thrown down at a speed above terminal velocity. Sketch a VT graph and describe its motion.A skydiver with a mass of 85 kg. They jump out of an airplane.Describe her motion for the first few seconds.When they reach terminal velocity, what is the force of air resistance acting on the skydiver? Include a FBD.The skydiver now opens her parachute. Draw a FBD at that instant.She then lands safely on the ground. Draw a VT graph for her entire jump. ................
