Newton's Laws

For every action force there is an equal and opposite reaction force

• Newtons (N)

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newtons (N)

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

ALWAYS cause a change in motion. They are NOT equal in size, but ARE opposite in direction.

• balanced forces

• Law of Inertia

• pairs

• unbalanced forces

A push or a pull resulting from the interaction of an object

• balanced forces

• Law of Inertia

• pairs

• unbalanced forces

The change in velocity (speed and/or direction) over time

• velocity

• less Inertia

• more inertia

• acceleration

The change in velocity (speed and/or direction) over time

• friction

• gravity

• inertia

• acceleration

DO NOT cause a change in motion. They are EQUAL in size and ARE opposite in direction.

• balanced forces

• Law of Inertia

• pairs

• unbalanced forces

This force pulls all objects to the ground with the same acceleration

• friction

• gravity

• inertia

• acceleration

The amount of matter in an object

• friction

• mass

• inertia

• acceleration

Objects with smaller masses have

• friction

• more inertia

• less inertia

• acceleration
