Energy Forms and Transformations

Multiple Choice

What is the difference between mass and position as described in the vocabulary slide?

• Mass is how much matter there is in something, while position is where an object is relative to a point of reference.

• Mass is where an object is located, while position is how much matter there is in something.

• Mass and position both describe the amount of matter in an object.

• Mass and position are both measured in grams.
