Notes:

Frame of Reference:

Motion is relative.  It needs to be related to another object to have meaning.

    If you are riding in a car with your friend, your friend will appear at rest.  An outside observer, though, will view both you and your friend as speeding by.  The car is your frame of reference while the Earth is the outside observer's frame of reference.
