Newton's Laws of Motion!
Created by the almighty Karissa Donawho
Newton's 1st Law of Inertia
An object at rest will stay at rest unless acted on by an unbalanced force and an object in motion will stay in motion at the same speed and direction unless acted on by an unbalanced force.
This means that if something is at rest, nothing will make it move unless a push or pull is acted upon it. An object will keep moving until a push or pull stops it.
Newton's 2nd Law of Acceleration
The acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force applied.
This means that more force is needed towards an object of large mass and less force is needed towards an object of less mass. The accelaraton is greater, as the amount of force increases.
Newton's 3rd Law of Action/Reaction
For every action, there is an equal and opposite reaction.
Everything that occurs, has a reaction with the same amount of force applied when it ocuurred.
Inertia #1
In the picture shown, it illustrates a wind spinner.
The spinner to the left shows that there is no motion because there is no wind (unbalanced force) to push it. Therefore, it stays at rest,
The spinner to the right shows that there is wind (an unbalanced force) pushing it, causing the spinner to spin.
No wind is no fun...
Acceleration #1
On the left, the chair is lighter, 134 grams to be specific. If a student were to pull it out, the acceleration would be much greater than when the same student pulls out the dinner chair on the right that's 344 grams. This eans that more force is required!
Lets just say there's a mini workout before sitting down to eat...
Action/Reaction #1
The action is him falling towards the ground with a force of 24N, The reaction shows the ground (unbalanced force) pushing back against him with the same force, causing him to arise again from impact.
The result of this childish stunt was a bloody nose and pure embarassment,
(Do not try this at home)
Inertia #2
Then, all of the sudden, a dog runs and jumps on the little boy (unbalanced force), startling him.
The result of the dog doing so, was the boy turning over, in agony. The dog ALSO gets a spanking from the mommy, and the child is now angry and seeks revenge upon the pet.
Acceleration #2
This picture is advertising Wal-mart:
Save money. Live better.
Action/Reaction #2
This causes the dummy to shoot back with the same amount of force, and land with a loud *PLOP*. (Reaction)
The dummy is injured, but since he/she cannot feel, it doesn't really matter!
