Newtons bio
All force is measured in newtons.The first law states how an object will chnge motion unless acted upon.
The second law states that the force of an object is equal to its mass times the acceleration.The third law states that for every action there is a reaction.

NEWTON'S FIRST LAW

• An object will not change its motion unless a force acts on it
• An object at rest will remain at rest until something pushes it or pulls it
• An object that is moving remains moving until something pushes or pulls it
• All objects resist having their motion changed.
• A soccer ball being kicked is a example of an object changing motion.

NEWTON'S FIRST LAW INERTIA

• Inertia is the tendency to resist a change in motion.
• The more mass an object it has, the greater its inertia.
• The less mass an object has, the less its inertia.
• Since a car has alot of mass you need a greater amount of energy needed to
• move it

NEWTON'S SECOND LAW

• The second law states that the force of an object is equal to its mass times the acceleration
• A net force changes the velocity of an object, and causes it to accelerate
• A change in motion occurs only if a net force is exerted on an object
• If an object is acted upon by a net force, the change in velocity will be in the direction of the
• net force

NEWTONS SECOND LAW ACCLERATION

• The acceleration of an object depends on its mass.
• The more mass an object has or the more inertia it has, the harder it is to
• accelerate.
• More mass the less acceleration if the force acting on the objects is the same.
• A car takes a while to accelerate once it turns on.

NEWTON'S THIRD LAW

• The third law states that for every action there is a reaction
• When one object exerts a force on a second object, the second object exerts
• an equal force in the opposite direction on the first object
• The force exerted on the first object is the action force
• The force exerted on the second object is the reaction force

ACTION AND REACTION

• "What comes up, must come down"
• When you jump off the ground the earth pushes you up.
• Pushing down on the ground is the action.
• And the earth pushing you up is the reaction.
• The action is always first otherwise the reaction couldn't occur.
