ShareForce & Motion - Let's Get Moving!
You seem to be continually on the move. You are. There are times that you move fast and times that you move slow. In this section you will learn what makes you go and what determines how fast you get there,
Have you ever wanted to do things the easy way? How much effort do you actually have to put forth to get the greatest result?
Let's take a look and maybe try a thing or two
Let's get different kinds of balls together to try this activity. Try using a beach ball, a golf ball, basket ball, and a round balloon.
Lay all four balls on a flat surface. Are they moving? (I think not!) How are you going to get the balls to move without touching them? You are full of hot air if you think about it. Try blowing on each ball with some of your hot air. Blow on each ball one at a time. How far did they move? The beach ball probably moved slightly and the balloon probably moved the farthest. How hard did you blow? Were you able to get the golf ball to move? How about the basketball; did it move? Be a little more forceful! Use a feather to move each object. Which ones moved the farthest? Don't give up if they didn't all move. Let's try something with a little more force. Use your finger (only one). Were these results better? Why or why not? Now even more FORCE! Use the palm of your hand. Which one moved the farthest?
| Object | Blowing Air | Feather | One Finger | Palm of Hand |

| Golf Ball | ||||
| Round Balloon | ||||
| Beach Ball |
Did any object move with each type of force applied?
Now try moving other objects of different shapes and sizes. You may try something from the list below or a different object with adult permission.
- Chair
- Pillow
- Pan
- Pencil
- Book
- Plate
- Toy car
- Football
Analysis:
- If each object is on a flat surface, which one will be the easiest to move?
- Which objects will require the most force to move?
- Why are some objects more difficult to get to move?
Remember that sometimes you just need to put forth a little more effort.
