Displacement Nearly the first thing you must do in every Physics problem is define a coordinate system. Choosing the proper coordinate system can make a huge difference. For one dimensional motion it is rather easy. 1) Choose an origin. 2) Choose a positive direction. 3) Stick to your choices throughout the problem!

Displacement x is defined as the position compared to the origin. x can be a positive or negative value. Displacement, x, is a difference between positions. x = x 2 –x 1 x can be a positive or negative value.

Displacement Distance, d, is the total length travelled. d can only be a positive value. For many problems, we will be dealing with an object in motion. Thus, the position, x, will change with time, t.
