September 28th – Jingjing Chen In Class today the questions given the previous day (P45-47 #1-8, P49 #1.1, 1.3, 1,4, P58 AC #1-3, 8, 9) were went over. A question from Adam Gruel was answered with all haste, but its significance was minimal and therefore, shall be excluded from this summary. Velocity Time Graphs Distance Time Graphs Scalar > Magnitude, Unit Vector > Direction Positive displacement = + velocity Negative displacement = - velocity d/t < v/t d = positive (No Time Travel Whatsoever)
Basically, Delta D / Triangle T We also went on to describe a classic problem. Velocity when a person throws a ball up into the air. The ball starts out with fast velocity before slowing down and eventually reaches zero velocity before beginning its fall and speeding up. Distance Time Graph Velocity Time Graph
