...so good to me (or is that Monday, Monday?) Bungee jumping in Physics, tug of war in Honors Physics and the fun of friction in Physical Science. The bungee lab did a good job of demonstrating the changes in acceleration produced by forces. Free-fall with a slack elastic and an abrupt acceleration when the elastic applied its force on to the jumper. Very nice graphs and no bungee jumpers were harmed in the experiment. Newton's 3rd law of motion was so well demonstrated in Honors Physics lab that the graphs could have been framed. Perfect mirror images for the action/reaction forces regardless of whether they were applied through an elastic or non-elastic cord. Those who got to do the extension saw that the graph patterns could not have been produced by any action by a lab partner. Inanimate objects also produce forces and follow Newton's laws. Physical Science got a yap-fest about balanced/unbalanced forces and the specific force of friction. We are going to explore these concepts in Monday's lab and then launch into a more in-depth examination of the effects of forces on motion.
