Document Summary

Lecture 1: course overview & overview of mechanics. Explanation of why motion occurs, and mathematica precise relations between causes of motion and resulting effects. Video will be posted online to be analyzed: 2 objects travelling at different constant speeds, a ball is tossed between 2 subjects. At constant speed: a ball is tossed upwards and then caught (upward projectile motion. ) Motion diagrams: motion in a straight line at constant speed. Objects in motion can be simply represented as a dot (or their center of gravity) in order to simplify motion diagrams. The simplest motion is no motion, or a stationary object. Constant speed is indicated by a motion diagram similar to the one seen above, that is that the same amount of time elapses between each dot on a motion diagram. Increasing speed: an object is speeding up, which can be seen as an increase in distance between the dots in a motion diagram.
