Lesson 1: How far do we really go at the end of the day? Exploring the difference between distance and displacement.
Worked example of calculating displacement from time and velocity. Learn how velocity, time, and direction factor into calculating displacement. Understand the importance of unit conversion in these calculations.
Displacement in physics is a vector quantity that measures the change in position of an object over a given time period. Learn how to calculate an object’s displacement as a function of time, constant acceleration and initial velocity. Created by Sal Khan.
A fourth equation can be useful when acceleration is known to be constant, but its value is unknown. This equation can be derived by combining two equations for average velocity. Average velocity is defined as displacement divided by the time during which that displacement occurred: v a v g = x − x 0 t.
