Newtons Laws

By Nick Failla

Newtons 1st Law

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

This picture shows how Newton's law works because it shows a ball staying still without a force. The ball will always stay still unless a force is applied, in that situation then force would be him kicking the ball. The ball would always stay in motion unless acted on by an external force which would be friction if the ball kept rolling.

Newtons 2nd Law

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

The picture shows the more force you put on an object the faster or movement it will have.

Newtons 3rd Law of Motion

For every action there is an equal and opposite reaction.

The picture shows the action, the ball falling. The opposite of the ball falling would be hitting something that interrupts that action, after the ball hits it will bounce, going up for a matter of time until the opposite happens again.

A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
