PRESENTATION OUTLINE
Newton's First Law
An object at rest remains at rest and an object in motion remains in motion unless acted on by an outside force.
This car will remain at rest until someone starts to drive or pushes it. The car will remain in motion until someone steps on the petal to stop it.
The girl will remain at rest until she pushes her off the wall. She will stay in motion until something stops her.
The nail will remain at rest until the hammer hits it. The nail will remain motion until the hammer stops.
Newton's Second Law
The force acting on an object equals the object's mass times its acceleration.
The amount of force the guy applies to lever will tell the ball how far to go. The harder he hits the farther and faster the ball will go.
The amount of force the ice skaters use will determine how far they will accelerate away from each other.
The boy with the big rock will need more force then the little rock because the bigger rock has more mass. The little rock will accelerate faster because it has less mass.
Newton's Third Law
For every action, there is an equal and opposite reaction.
The action is the air coming out if the balloon and the reaction is the balloon going up.
The action is the gun being shot and the reaction is the guy falling backwards.
The action is the arm pushing the water and the reaction is the body moving forward.
