Building on the concept of inertia, Eureka! adds the factor of mass, tells how it's measured, and shows how it differs from size. Concept: Inertia increases with mass. Eureka was a series of short cartoons on physics that ran on public television in ...the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Using Avogadro's law, the mass of a substance can be related to the number of particles contained in that mass. Chemists have learned how to count molecules by weighing macroscopic amounts. Chemists must measure precise amounts for reactions to occur... in an accurate manner. Analytical data and masses from the atomic chart are used to determine the number of atoms in a given volume.

What is mass and where does it come from? Video explains mass, inertia mass of an object, and what causes mass. There are many things about mass which we don’t know. Mass has two definitions, one is gravity, the more massive an object is the more m...assive the gravity. The second is how much something doesn’t like to be pushed around. So, the higher the mass the more you have to push it. The video also gives examples to these two definitions. Video is of good quality. Video would be good for middle elementary, middle and high school students. This is an interesting video for any student studying electric charge. Run time 08:38.

Introduction to the center of mass. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification.
