How is weight and mass different?

Mass is defined as the amount of matter an object has.

The weight of an object depends on gravity.

A frog will have a mass of 2721 grams on Earth and on the Moon.

A frog will weigh 8 pounds on Earth, but 1.32 pounds on the Moon.

Density is how heavy something is for its size.

Density is found by dividing mass by volume.

Density = Mass

Volume
