The law says that every action has an opposite reaction.
We proved this when Laura and I did an experiment.
We both sat on carts.
Then i pushed as hard as i could on laura's knees.
Instead of having laura just move back, i did too because she pushed back on me.
Even thought she didn't really notice she was pushing, she was, because i moved back.
If she didn't push on me then i wouldn't have moved.
We also saw Mr. Finley do an experiment.
He was standing on a cart and pushing or pulling on the door handle.
When Mr. Finley was on the cart, he tried to open the door but the force of the door pushed him away.
When he was holding the door shut, the force of the door made him come towards it.
What is the real world application?
- It shows that no matter what force it is, there will always be something pushing back on you. Also there is always the earth's force which is gravity.
