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.
Adam and Jamie test the classic myth about seeing if any amount of force can separate two phone books when the pages are interwoven. Tory, Grant, and Kari team up to investigate a movie scene with explosions, harpoons, and sharks! Science topics discussed include static friction, kinetic friction, forces, small scale testing, Newton’s Third law of Motion, equal and opposite reactions, tension, chemical reactions, projectile motion, projectile accuracy, shock waves, energy dissipation, and organ trauma.
Adam and Jamie test the classic myth of pulling a tablecloth out from underneath dinnerware. This is the perfect episode to demonstrate Newton’s First Law of Motion, the Law of Inertia: An object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an outside force. Meanwhile, Tory, Grant, and Kari test the myth that we use only 10% of our brain. Science concepts discussed include Newton’s First Law of Motion, Law of Inertia, static friction, inertia, momentum, mass relationships, small scale testing, frictional coefficients, material selection criteria, electroencephalograms, EEGs, brain lobes and functions, parietal lobes, frontal cortex, occipital lobe, magnetoelectroencephalograph, MEGs, functional magnetic resonance imagining, FMRIs, and comparative base line data.
