Free+Fall

This is an exciting time... http://www.xkcd.com/1071/

Start at section 2.5 and look over the four one-dimensional kinematic equations (equations 2.6, 2.8, 2.9 and 2.10). Even though they look a little different, we have used three of these before. One of them (2.10) is a new one which combines two of the previous equations. Please practice using the equations in this new format - you will be writing them this way from now on.

Read section 2.6 regarding free fall.

A recreation of the experiment that probably didn't happen. At the end there is a good explanation of why free fall is independent of mass. media type="youtube" key="_Kv-U5tjNCY" height="315" width="420"

(Just a reminder: don't forget your summer reading assignment and remember to buy a lab notebook before school begins.)
