Newton's 1st law of Motion

Objects remain in uniform motion (at rest or constant velocity) until acted on by a net force.

Newton's 2nd Law of Motion

A net force exerted on an object results in acceleration proportional to the strength of the force and inversely proportional to the mass of the object.

Newton's 3rd Law of Motion

For every action the is an equal and opposite reaction.

Force

(F): An interaction between masses.

Force Equation

F=ma, measured in Newtons (N).

Mass

(m): A measure of the quantity of matter in an object.

Inertia

The property of mass that resists change in motion. Large masses have a lot of inertia.

Balanced Force

Equal forces acting on one object in opposite directions.

Unbalanced Force

Unequal forces acting on an object cause motion.

Net Force

The sum of all the forces acting on a mass.

Newton

(N): The unit used to measure force in the metric system.
