Chapter 5 WebLab#2: “Inclined Plane” Notebook Section #10 * Go to the following website: http://www.ngsir.netfirms.com/englishhtm/Incline.htm * Push “start” to begin the simulation. The box will slide down the frictionless incline and then perfectly bounce back and then go back up the incline. Observe the motion, and then observe the graphs of kinetic, potential, and total energy at the top of the page. * Repeat the experiment, but move the red circle at the bottom of the hill to increase the angle of the incline without changing the height of the incline. (You can make the hill as tall as possible by pulling the red circle straight down until it stops.) Look at the red velocity vector to get a sense of the speed of the block. Observe the motion, and then observe the graphs of kinetic, potential, and total energy at the top of the page. * Repeat the experiment, but now set the friction coefficient to 0.3 with the slider at the bottom of the screen.

Unformatted text preview: Observe the motion, and then observe the graphs of kinetic, potential, and total energy at the top of the page. * Repeat the experiment with the same friction coefficient but a different ramp angle. Observe the motion, and then observe the graphs of kinetic, potential, and total energy at the top of the page. Questions: 1) What happens to the kinetic energy as the block moves down the frictionless hill? What happens to the potential energy? What happens to the total energy? 2) What effect does increasing the ramp angle ( but not changing the ramp height ) have on the motion of the block on the frictionless incline? 3) What happens to the kinetic energy as the block moves down the hill with friction? What happens to the potential energy? What happens to the total energy? 4) What effect does increasing the ramp angle ( but not changing the ramp height ) have on the motion of the block on the ramp with friction?...
