A student claims that mass and weight are the same because they both increase if you add more matter to an object. How would you respond to this claim using scientific reasoning?

• Mass and weight are the same because they both use kilograms as units.

• Mass is the amount of matter and does not change with location, while weight is the force of gravity on that mass and can change depending on where you are.

• Mass and weight are both forces, so they are the same.

• Mass and weight both depend on gravity, so they are identical.

• It is twice as much because gravity is weaker.

• It is the same because mass does not change.

• It is half as much because weight depends on gravitational acceleration.

• It is zero because there is no gravity.

A scientist measures the mass and weight of an object at the top of a mountain and at sea level. The mass remains the same, but the weight is slightly less at the top of the mountain. What does this observation tell you about the relationship between mass, weight, and gravity?

• Mass and weight both change with altitude.

• Mass changes, but weight stays the same.

• Weight depends on gravity, which can vary with location, but mass does not.

• Both mass and weight are independent of gravity.
