< < Lecture 9 Lecture 11 > > PhET Projectile Motion Simulation Change the angle of a cannon and the starting velocity of a projectile to see how it changes the path of a projectile that it launches. You can also change the height of the cannon to see how Read more…
< < Lecture 8 Lecture 10 > > Resources Newton’s Embarrassing Secret – Start watching at 9:52 to see the chapters of The Elegant Universe about squaring up Newton’s Law of Universal Gravitation and what we know about the “universal speed limit” from Einstein’s theory of relativity. PhET Gravity and Orbits Simulation Read more…
< < Lecture 7 Lecture 9 > > Resources “Dancing” t-handle in zero g – Watch a video of a T-handle as it rotates about its intermediate axis, causing the rotation to be unstable. (An object that spins about its longest or shortest axis is stable, rotation along the intermediate Read more…
< < Lecture 6 Lecture 8 > > Resources Bed of nails – Watch as Dr. Fazzini hits me with a sledgehammer as I lay on a bed of nails during STEM-CON. I don’t get injured because the kinetic energy from the sledgehammer is used up breaking the brick. This Read more…
< < Lecture 5 Lecture 7 > > Resources Understanding car crashes: it’s basic physics – This YouTube video explains the physics of car crashes and safety features in cars. If you’ve ever wondered why seatbelts and airbags work, this video will answer your questions! Video Transcript Hello there! Welcome Read more…
< < Lecture 4 Lecture 6 > > Video Transcript Hello there! Welcome to lecture five: Newton’s third law! Newton’s third law describes the forces that exist between two objects when they interact. This helps us understand the physics of lots of everyday motion: why we move when we walk, Read more…
< < Lecture 3 Lecture 5 > > Resources Feather and hammer drop on the moon – Watch what happens to the motion of a feather and a hammer in complete free-fall. Because the moon has no atmosphere, there is no air resistance to counteract the effect of gravity. (This Read more…
< < Lecture 2 Lecture 4 > > Video Transcript Hello there! Welcome to lecture 3: linear motion! Linear motion allows us to start exploring kinematics, which is the study of the motion of objects. The topics in this chapter will allow us to answer the questions of how far Read more…
< < Lecture 1 Lecture 3 > > Resources Vector addition: does order matter? – Play with this interactive simulation to see if the order in which you add vectors matters. PhET Vector Addition Simulation The PhET vector addition simulation is a great way to practice using vectors. Use the Read more…
