Forces Unbalanced/Balanced + Gravity

Forces Unbalanced/Balanced + Gravity

What is a force?

• A force has strength and direction

What is a balanced force?

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

• Think of them as canceling each other out

What about an unbalanced force?

• 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

What is the physical science term for a PUSH or PULL on an object?

• Motion

• Force

• Friction

• Gravity

Gravity

• A pull toward the most massive object nearby

• Mass means how much stuff something has

• Gravity moves around the speed of light

Mass is a measure of the amount of matter in an object. 

• 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.
