Forces Unbalanced/Balanced + Gravity

A force has strength and direction

When two forces that are the same size (amount) act in opposite directions.

Think of them as canceling each other out

When a force is not opposed, it is unbalanced

An object will start to move in the direction of an unbalanced force

More than one force can add together in the same direction

A pull toward the most massive object nearby

Mass means how much stuff something has

Gravity moves around the speed of light

Mass is usually measured in grams (g) or kilograms (kg).

Mass measures the quantity of matter (how much matter something has)

Mass is the same regardless of the object's location in the universe

Mass is the same regardless of the gravitational force applied to it.
