Lesson 1 : Matter !

Lesson 1

Do you know what matter is? 

Matter is anything that has mass and takes up space,however not everything is matter. 

For example: light and sound are not matter, but a pencil or a book are matter.

Mass is the amount of matter in an object.
Weight is a measure of the gravitational force.An object´s weight can change depending on the object´s location. For example: You would weigh less on the moon than you do on Earth because of the gravitational force.

 Volume: the amount of space that an object  takes up.
Density : the amount of mass in a given volume.

Formulas: 

To find an object´s density you have to divide its mass by its volume.

To find an object´s mass you have to multiply its density and its volume.

To find an object´s volume you have to multiply length, width and height
