Newton's Laws

Newton's 1st Law

An object at rest will remain at rest and an object in motion will remain in motion, unless acted on by an unbalanced force.
Also called the "Law of inertia

Inertia

The tendency of an object to resist any change in motion

Newton's 2nd Law

Acceleration is produced when a force acts on a mass.

Force

a push or pull on an object; measured in Newtons (N)

Mass

The amount of material/matter in an object

Friction

A force that opposes or slows down motion

Gravity

A force that always attracts or pulls objects toward each other without direct contact or impact

Newton's 3rd Law

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

Balanced forces

Equal forces acting in opposite directions causing no change in motion

Unbalanced forces

forces not equal in size that cause the motion or direction of an object to change

net force

the sum of all forces acing on an object.

momentum

The product of an objects mass and velocity

Weight

A measure of the force of gravity on an object

mass

A measure of the amount of matter in an object

kinetic energy

Energy of motion

potential energy

stored energy or energy of position
