Video Demo: Fishing Weight Inertia

The more mass an object has, the more inertia it has.  Inertia is the tendency of an object to resist a change in motion.  There are two fishing weights.  One has more mass than the other.  A string applies an unbalanced force to the different weights.  Which one resists a change in motion?  Watch the video.


Video Demo: Beaker Inertia

Another demo on inertia?  Yup, and this time I have enlisted the help of one of my favorite science guys: Beaker.  Beaker, books, and a rolling chair are moving at constant velocity until an outside unbalanced force is applied.  Watch what happens!


Video Demo: Ring Inertia

I shot a lot of video before the end of school, and here is a favorite but simple one of mine.  All you need is some chalk (or pennies), a wooden ring (from a craft store), and a flask.  Watch the video.


Video Demo: Egg Inertia

I've posted this demo on the site before, but now I have it in high definition.  It's a classic experiment showing the principle of inertia in action.  Watch the video!


Video Demo: Laser Light Behavior

Light can be absorbed, transmitted, reflected, refracted, and/or scattered.  In this simple video, laser light is transmitted through glass, reflected off a mirror and refracted through a prism.
