Mass/volume/weight review

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, typically measured in newtons (N).

Front

How does gravity affect weight on different planets?

Back

Weight varies depending on the gravitational pull of the planet. For example, an object weighs less on the Moon than on Earth due to lower gravity.

Front

What is mass?

Back

Mass is the amount of matter in an object, measured in grams (g) or kilograms (kg), and does not change regardless of location.

Front

Does mass change when an object is on the Moon?

Back

No, mass remains the same regardless of location, whether on Earth or the Moon.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and the acceleration due to gravity (Weight = Mass x Gravity).

Front

What is volume?

Back

Volume is the amount of space an object occupies, measured in liters (L) or cubic centimeters (cm³).

Front

Does air have mass?

Back

Yes, air has mass and takes up space, which is why it can exert pressure.

Front

What tool is used to measure mass?

Back

A balance scale is used to measure mass.

Front

If an object has a mass of 10 kg on Earth, what is its mass on the Moon?

Back

10 kg (mass does not change with location).

Front

What two factors does gravity depend on?

Back

Gravity depends on mass and distance between objects.
