Motion

Today in class we discussed motion and in particular Projectile Motion. First, we started off reviewing Newton's second law of motion which is F=ma. We also reviewed that mass is constant and weight depends on where you are. In the end we came up with the Inverse Square law which is: 1/r^2 and learned that the closer together two items are the more force. Then we moved on to Projectile Motion in which we watched a simulation with a cannon. First, the cannon was shot at 90 degrees and the cannon ball went up and came back down. Next, the cannon was shot at 70 degrees which created a parabola effect. Then the professor asked what degree would send the cannon ball the farthest ? One student suggested 45 degrees and she was correct. We checked other numbers and realized this was the degree that would have the ball go the farthest. This simulation was with no air resistance.
In class today we went over some difficult information as a class. The simulation did help to get the Projectile Motion across. It was a neat way to see what we were learning.
