Notes Write down the words in yellow. The words in white are discussion points, you may write these down, but are not required.

Mass & Matter Mass – The amount of matter that makes up an object. Matter – Anything that has mass and takes up space

Mass & Motion An object’s mass determines how much a force will change its motion. The greater the mass of the object, the greater the force will be needed in order to affect it.

Mass & Motion Suppose you use a Ping-Pong paddle to hit both a bowling ball and a Ping-Pong ball. The mass of the bowling ball is much greater than the mass of the Ping-Pong ball. If you hit both balls with the same force, the Ping-Pong ball will move faster. It will also move farther.

Mass & Motion Now suppose you have an empty wagon you want to use to move a pile of books. The mass of the wagon when it is empty is less than the mass of the wagon when it is loaded with books. When you load the wagon with books, its mass increases. The greater the mass of the wagon, the less your pulling force affects its motion. If you pull the full wagon with the same force you used when it was empty, its motion will be less affected. The full wagon will move more slowly than when it was empty.
