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.

Why is it harder to push a wheelbarrow full of stones compared to an empty one?

• Because it has more mass

• Because it is more colorful

• Because it is larger

• Because it is heavier

What remains constant for an object regardless of its location?

• Its weight

• Its color

• Its mass

• Its volume

What force is responsible for keeping Earth in orbit around the Sun?

• Electricity

• Gravity

• Friction

• Magnetism

How does the weight of an object on the Moon compare to its weight on Earth?

• It is half

• It is about 1/6 of its weight on Earth

• It is the same

• It is double

If a car's weight changes on the Moon, what happens to its mass?

• It remains the same

• It decreases

• It increases

• It becomes zero
