![]() ![]() Thus, by x we mean a change in position or displacement. In physics, work is the energy transferred to or from an object via the application of force along a displacement. The Greek letter, pronounced Delta, indicates a change in some variable. The distance traveled, however, is the total length of the path taken between the two marks. displacement final position initial position, x x f x i, where x i is the initial position and x f is the final position. ![]() The displacement is simply the difference in the position of the two marks and is independent of the path taken when traveling between the two marks. One way to think about this is to assume you marked the start of the motion and the end of the motion. After all, the position of the ball didn't change. So, the angular displacement of completing a full rotation counterclockwise (2 pi radians) may appear to be 0. That is because angular displacement is how much has the angle moved. In kinematics we nearly always deal with displacement and magnitude of displacement and almost never with distance traveled. The formula for angular displacement is not Pf - Ps, where Pf is final position and Ps is starting position. ![]() In this case her displacement would be 2 m 2 \text 1 5 0 m 150, start text, space, m, end text. For example, the professor could pace back and forth many times, perhaps walking a distance of 150 meters during a lecture, yet still end up only two meters to the right of her starting point. By magnitude, we mean the size of the displacement without regard to its direction (i.e., just a number with a unit). People often forget that the distance traveled can be greater than the magnitude of the displacement.
