This program introduces the series and sets forth the concept of inertia, the first law of physics: Things like to keep on doing what they're already doing. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in a simple and well-illustrated way. Good for students of any elementary school level. The 'meat' of the video starts at 01:28.
