displacement vs. distance traveled If a body with position function s (t) moves along a coordinate line without changing direction, we can calculate the total distance it travels from t = a to t = b.
Distinguish between displacement and distance traveled. Calculate displacement and distance given initial position, final position, and the path between the two.
To determine the displacement of an object, you only have to consider the change in position between the starting point and the ending point. The path followed from one point to the other does not matter.
2.6 Displacement vs. Distance vs. Distance traveled 14 •Displacement from P to R •-0.8 m •Only depends on starting and ending point •Distance from P to R •This is just a scalar quantity 0.8m •Distance traveled on the path from P to R is: •4.4m •Depends on path taken, but is always positive. See Example 2.7 in text
Flipping Physics Lecture Notes: Introduction to Displacement and the Difference between Displacement and Distance. Displacement: The straight-line distance between the initial and final points. The symbol is Δx, where Δ means “change in” and x means “position”. The change in position of an object.
(a) Discuss with a classmate how using a particle’s displacement equation can help you find a particle’s velocity equation. Also, discuss how you using a particle’s velocity equation can help you find the particle’s acceleration equation. Share your results with the class.
Introduction to Displacement and the Difference between Displacement and Distance. Displacement: The straight-line distance between the initial and final points. The symbol is Δx, where Δ means “change in” and x means “position”. The change in position of an object. Δx = xf – xi (read, displacement equals position final minus ...
