Conversions and Graphing Lectures

This lecture describes how to convert within the metric system itself. It discusses the metric prefixes used in science, and how a simple movement of decimals allows for quick conversions. (NOTE: This does not cover scientific notation, something I do later in the eText).

In this lecture, I discuss how to use dimensional analysis to convert metric units into their standard SI unit. This will work for any dimensional conversion, including Imperial units to SI

In this lecture, I discuss some basic rules for making a line graph in Physics. This is largely if doing by hand, graphing by computer is better.

In this lecture, I review the way to calculate the slope of a line graph, including how units fit in with the answer.

In this lecture, I discuss how to find the resultant of a set vectors that act along the x-axis and y-axis. This does not discuss if the set of vectors have any angle, but does discuss how the resultant can have an angle. Also, I do not go into the rules of trigonometry, but discuss how the trig simply works.

In this video, I discuss how to find the resultant of a set vectors that act along the x-axis and y-axis, and also includes vectors with angles.  Also, I do not go into the rules of trigonometry, but discuss how the trig simply works. The rules I apply are not the way it is typically done in a math class, but works well enough for what we do in basic physics.
