TJ's Physic's class is studying the basic laws of motion. For his final project he was required to construct a roller coaster. They could use anything they wanted except pre made kits. TJ's idea was to use a marble and wire. He had a few unsuccessful attempts with thin wire and balsa wood. Instead of giving up, trial and error was the name of the game. I think he really learned a lot and thoroughly grasped the concept. He got thicker wire and redesigned his coaster. He soldered the wire together with cross beams and widened the rails which made it much easier to control the angle and direction of the rails (slope, vector).
Newton's Three Laws of Motion
Let us begin our explanation of how Newton changed our understanding of the Universe by enumerating his Three Laws of Motion.
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
III. For every action there is an equal and opposite reaction.
Cal and Karrick were mesmerized and built their own marble coaster on the floor using household items. (not shown)
TJ was itching to use spray paint
The finished product and TJ is doing his presentation at school today. I love projects that inspire kids to think and be creative. If you enlarge this picture (click on it) you can see where TJ had to label in pencil the laws of motion
