What is the Difference between Mass and Weight?

Weight

Mass

#### Mass is a measurement of how much matter an object has. Matter is every object around you because it is anything that takes up space .The larger the matter is of an object the greater the mass will be. Though if something is the same size like a bowling ball and a balloon, which would have more mass?

 This picture shows two item to help you realize the meaning of mass.

Which do you think has more mass? The mouse or the truck?

Isaac Newton

#### Gravity is a pulling force that works across space. Isaac Newton discovered the law or truth about gravity in the late 1600s. Newton was an English scientist.After his discovery it helped realize the difference between mass and weight.

 This is a portrait of Isaac Newton.

Gravity

#### If you had a Ping-Pong ball and a soccer ball which would gravity pull on more? The soccer ball since it has more matter and mass. Another example is that if you had an empty jar, it would be very light. Though if you added some soup into the jar it would be heavier because gravity is pulling on it more.

What is the Difference between Mass and Weight?

#### From what you learned you probably can now see the difference. Well mass is the measurement of the amount of matter something has and weight is a measure of the force or gravity between the object and the surface it stands on. This means that weight changes due to the cause of gravity but mass never does. You as a person can not change in mass unless you are growing. If you went into outer space you would see that you don't change in size. Though you weight would be different because without gravity you become lighter since no force is pulling you.
