Let's Get Moving!

 
In this first activity you will see that objects at rest (not moving) won’t move unless a force is applied to them.
 

Put your pencil on the table next to you. Don’t touch it, and don’t bump the table. What is your pencil doing? Hopefully it is just sitting there quietly.

No force has been applied to the pencil, so it just sits there. Remember, a force is a push or pull.

 
Now think of ways you can move the pencil.
 
Push it!
Blow it!
Jab it with your mouse!
 
Each of the pictures shows a force being applied to the pencil. When the push or pull is applied, the pencil moves. The direction and speed of the movement depends on the force you apply and what it is you are trying to move.
 
Some things are easier to move than others. The pencil was pretty easy. It is light. You can even move it just by blowing. What about a chair? It will need a stronger force than just blowing. What about a boat on a trailer? Maybe a truck would help!
