What is the term for a coordinate frame within which to measure position, motion, or other properties of an object?

• Scalar Quantity

• Frame of Reference

• Displacement

• Vector Quantity

Why is it not ideal to use another moving car as a frame of reference to describe your own motion?

• Because it is stationary

• Because it is not visible

• Because it is moving with you

• Because it is too far away

How is distance defined?

• The speed of an object in a specific direction

• How far an object travels, regardless of direction

• The rate at which an object is moving

• The difference between an object's final position and its starting position
