"To teach her students about velocity, teacher Ethel Locke set them loose in the halls of Woonsocket High School with marble launchers.
Through trial and error, the students discovered that their marbles achieved the longest arcs if they were launched at an angle halfway between the floor and the ceiling. If they set the launchers at higher or lower angles, gravity pulled the marbles to the floor at shorter distances."
Physics no longer a junior member
"Pausing from the task at hand, Devon confided that he liked physics better than he thought he would. Ordinarily, he said, it 'is not a class you would like.' "
That's because it isn't physics.
How about deriving the equations you need from g=32.174 ft/sec^2 and analytically calculating that angle.?
Does anyone have any experience with Physics First? The story claims that this order has "nearly doubled" the demand for AP science courses in physics, biology, and chemistry. They must have another senior-level AP physics course. This means that kids would take two physics courses in high school?
