Need help what it means to be comparing mass and weight? HomeworkUnlocked is here to help. While we expand our own lesson library, we’ve selected some educational videos from Creative Commons. This is a very brief video that outlines the basic units of mass and weight and explains the difference. Unfortunately, the video does not provide any examples but if you need a quick refresher on the different units of mass and weight this might be helpful.
