Newton's Laws Of Motion

By: Landree Yocom

Newton's First Law Of Motion

Inertia

An object will stay at rest unless acted upon by an unbalanced force.

AND

An object will stay in motion at the same speed and direction unless acted on by an unbalanced force.

Real Life Example

If you aren't wearing a seat belt while in driving a car, and you get in a reck; the car will stop, but you will keep moving because the seat belt is the unbalanced force that would stop you. while not wearing a seat belt you will end up flying out of the car.

Another example is, when you are holding a volleyball and are about to serve; you throw the ball up in the air.

Newton's Second Law Of Motion

Acceleration

The acceleration of an object by force is inversely proportional to the mass of the object, and directly proportional to the force applied.

Acceleration also is the rate of change in the motion of an object. This includes velocity, speed, or direction of an object.

Acceleration is any change in motion. For example, starting, stopping, speeding up, slowing down, and turning.

Real Life Example

A sports car v.s. a semi truck. The sports car has much less mass, so it will accelerate faster. So the semi truck has much more mass, and will accelerate a lot slower.


Another example is, when you blow up a balloon; the more air you blow into it, the faster it will accelerate.

Newton's Third Law

Action/Reaction

For every action, there is an equal and opposite reaction.

All forces act in pairs. An action force causes a reaction force that is equal in size, and opposite in direction.

Real Life Examples

A rocket taking off creates an action force of gasses pushing down that causes the reaction force of the rocket going up.
