Topic 7 - Relative Motion in 1D and 2D

Question 1

What is Relative Motion?

Answer 1

• Relative motion has everything to do with RELATIVE VELOCITY

* Vectors are crucial in calculating relative velocity

• The goal is to relate the measurements of two different observers, one moving with respect to the other

Question 2

Reference Frames

Answer 2

• A reference frame is simply a coordinate system

• Measurements of velocity depend on the
  reference frame of the observer

Question 3

There are two types of reference frames:

Stationary Frame of Reference

Relative to Earth:

Answer 3

Observer is on the ground

Question 4

There are two types of reference frames:
