NEWTONS LAW PROJECT

FIRST NEWTON'S LAW

• objects in motion tend to stay in motion unless acted on by some external force.
• an example would be when you're traveling in the car and you come to a sudden stop, your body leans forward depending on how sharp the stop was.
• If it werent for the tension in the seatbelt you would keep moving while the car stopped.
• Seatbelts are very important because of this law.
• If you dont wear seatbelts you could die if you go fast enough.

NEWTON'S FIRST LAW

• A soccer ball will not move until a person kicks it.
• The ball needs force to move.
• If it dosent get force it will sit there.
• Wind could move it if it was strong enough.
• Without a force its useless.

NEWTON'S SECOND LAW

• A bird flying is an excellent example of newtons first law.
• A body at rest, tends to stay at rest; a body in motion tends to stay in motion.
• The wings go down and air pushes on it making force and makes the bird flying.
• The bird is going at a constant velocity.
• The smaller the mass of the bird the faster it goes.

NEWTON'S SECOND LAW

• A tennis ball will go far because it dosent have much mass.
• Mass is not weight.
• It takes more force to change the state of motion.
• When the ball is flying the ball is pushing against air.
• A tennis ball will go further than a basketball, but not marble.

NEWTON'S THIRD LAW

• The forces exerted by two objects on each other are often called an action- reaction force pair.
• Either force can be considered the action force or the reaction force.
• You might think that because action-reaction forces are equal and opposite that they cancel.
• Forces can cancel only if they act on the same object.
• For example, imagine you’re driving a bumper car and are about to bump a friend in another car, when the two cars collide, your car pushes on the other car.

NEWTON'S THIRD LAW

• Newton's Third Law states that for any action force, there is always an equal and opposite reaction force.
• Imagine a cannon.
• As an explosion in the cannon forces the cannonball out of the cannon, an equal force pushes the cannon backwards.
• Cannons usually have more mass than cannonballs, so the cannon would not accelerate at the same rate as the cannonball would.)
• The third law is push or pull.
