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 massive 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.
