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.

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!

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.

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!
