What Is Matter?: Mass and Weight

The video explains the difference between mass and weight. It starts by comparing the difficulty of pushing a full wheelbarrow versus an empty one, highlighting that mass is the amount of matter in an object. The video then explains that while mass remains constant, weight can vary depending on gravity. It illustrates this with examples of how gravity affects weight on Earth and the Moon, noting that an object's mass does not change even if its weight does.
