A drift of reference toilet be mind of as any moorage your doing your streakment from as commodious as it is not accelerating. This is called an inertial frame of reference. 1-D Relative Motion causa 1: Lets take I am stand on the back of a pickup motortruck (that is motionless), and I am hold ining orchard orchard apple tree trees forwards.

How fast does my friend on the sidewalk say the apple is moving? ? Well, even before I throw it, shell say that the apple is moving at 20m/s (the speed of everything on the truck). ? When I have throw the apple forward, adding more fastness to it, she will say it is going away at (20m/s + 15m/s) 35m/s! ? Now I gambol around and start throwing the apples from the skunk of the truck, backward! ? I will still say that my apples are moving at 15m/s, because from my way of looking at it, thats how fast the apple is moving.
