Position and motion

Question 1

An object or location chosen to represent the origin (0,0) in order to describe the movement and position of other objects. They are chosen based on context, and what is most convenient.

Answer 1

Reference point

Question 2

Why do we need to create our own reference point?

Answer 2

Question 3

The distance of an object from a reference point

Answer 3

Position

Answer 4

Frame of reference

Question 5

A change in position

Answer 5

Motion

Question 6

What is the difference between distance and displacement?

Scalars

Question 9
