===== Week 11 Assignment: Total, Kinetic, and Potential energy Chart: (Original Geogebra Applet) =======
(Key: M = Mass (kg), V = Velocity (Meters/seconds), h = Height(Meters), TE = Total energy(N), PE = Potential energy(N), KE = Kinetic Energy(N) )
Questions
1. What happens when you double the velocity?
How does the kinetic energy change, and the Potential energy?2. Does changing the mass change the system, if so, how?3. What variable affects both charts when changed? Can you find it?
===== Classwork 12.2 Desmos app and Geogebra app (Hyperbola of two points app) =======
A cool rolling ball applet representation of a rollercoaster able to leave
the tracks.
This helps illustrate how engineers and designers must also be careful
when handling large amounts of potential and kinetic energy. (To avoid shooting passengers out! )
An applet simulator that allows one to edit the speed, gravity, mass and friction of a virtual coaster. By experimenting with these forces, we can gain a better understanding of them.
A interesting skate park simulator from university of Colorado on Mechanical and kinetic energy illustrating the effects as we increase and fidget as potential energy is converted into kinetic energy and vice aversa upon the ramps.
An applet of the forces of Friction and motion from University of Colorado, showing a instance of where, when friction is applied care must also be taken to account for it. While some of the earlier examples feature little to no friction forces, objects put into motions are eventually slowed by friction and converted to heat. Thus some potential energy and kinetic energy is lost as waste heat in the transactions.
A in depth collection of applets from University of Colorado covering a variety of subjects from physics, gases, and mechanics offering a fine insight into the mechanics behind our world.
A series of educational applets written to help visualize various concepts in math, physics and engineering from ripples, dispersion, loaded strings and membranes.
A great read on the mechanical forces behind Roller coasters, how we have Potential energy, Mass, gravity, and height and how they all relate to eachother to create the thrill seeking rides we've come to enjoy!
A really cool video on how to build a demonstration of a rollercoaster at home with nothing more than pipe and marbles, this could be used for a teacher to give a in class demonstration to a audience!
A informative and in depth video about the forces of G forces, Riders, physics, and how the rides make us feel heavier or lighter as we go up the rides alongside how feelings of multiple g forces or negative g forces make us feel like we're flying or soaring and how both weak and negative g forces are used in rides and sensations of total weightlessness to the viewer's perspective.
A interesting article on the physics of rollercoasters and how rollercoasters must carefully balance all factors such as G force, velocity, mechanical and kinetic energy and thrills through acceleration to create enjoyable and thrilling rides in highly engineered, unnatural ways by using Newton's laws of motions and how the way we experience the combined forces of gravity and acceleration leads to our thrilling rides.
A article from the Library of Congress on the physics of rollercoasters and why we don't fall out of a rollercoaster loop when we go in, and how engineers and designers must take careful track of testing and knowing a rollercoaster's limits and following industry standards and the vigorous tests. (Often first done with sandbags and dummies!) in order to ensure the rides are safe.
