First law

Every object continues in its state of rest, or uniform speed in a straight line, unless acted on by a non-zero force

Second law

The acceleration produced by a net force on an object is directly proportionate to the net force is in the same direction as the net force and is inversely proportional to the mass of the object

Third law

When one object exerts a force on a second object, the second object exerts an equal and opposite force on the first

Rule of adding/subtracting vectors?

Add if in same parallel direction

Subtract if in opposite direction

Subtract if in opposite direction

Greater mass = ....... acceleration

small

Smaller mass = ...... acceleration

large

Acceleration =

net force / mass

A = f/m

A = f/m

Weight =

Mass * Gravity

Friction

Force that acts between materials that touch as they move past each other.

Kilograms

The SI unit to measure mass.

Mass

How much "stuff" there is in an object.

Weight

The force of gravity on an object.

Newton

The SI unit for force.
