This is a computer lab that utilizes the Atwood’s Machine to explore Newton’s Second Law of Motion, F=ma. To access the lab, go to http://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Atwoods-Machine This lab has a total of 34 questions, covering six pages. A calculator is needed, but the math is very straight forward, essentially having the students plug in numbers for Newton’s Second Law of Motion, F=ma. Multiplication and division are all that is needed. Roughly about 30% of the higher-order questions are conceptually based off of the calculations and diagrams the students make in class.
Grant, Tory, and Kari test the myth that if you blow your own sail, you can move forward. Adam and Jamie explore the world of movie sounds to test if what you hear in the theaters resembles anything you hear in reality. Scientific principles alluded to include Newton’s First Law of Motion, objects in motion stay in motion, objects at rest remain at rest, Newton’s Second Law of Motion, F = MA, internal forces, external forces, force cancellation, net force, and free body diagrams.
Gravity (2013) is a stunning movie exploring the potential dangers of space and the physics behind them. This movie captivates the students through dazzling visuals, but the movie guide keeps them focused on analyzing the physics behind the scenes. Having said that, there are very accurate and inaccurate depictions of Newton’s Laws of Motion. But the inaccuracies add to the dramatic tension and advance the storyline of the movie. The movie guide is designed to have the students analyze the physics of the movie scenes, choose which of Newton’s Laws applies, and then describe why it applies or why it is inaccurate. The movie guide does not analyze the plot or emotional arcs during the movie, it just sticks to the physics behind each scene. The movie guide is best used for classes like physics, physical science, or astronomy.
First, the Mythbusters test the tale that a rocket propelled car can become airborne, then they examine the story that mixing Pop Rocks and soda can cause the stomach to explode. Science topics discussed include thrust and horsepower conversions, drag, aerodynamics, velocity, lift, forces and acceleration, free body diagrams, carbonation, gas pressure, organ elasticity, chemical reactions, chemical equations, and carbon dioxide formation.
