Using what we know about takeoff velocity and runway length to determine acceleration. [14:16]

Deriving displacement as a function of time, constant acceleration and initial velocity. [9:58]

Learn about vectors and scalars in physics, and find out how they are related to distance and displacement. [5:19]

This lesson explains how average velocity can be represented by a positive or negative sign. It is 1 of 2 in the series titled "Average Velocity & Sign Notation." [6:44]

Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Watch as Sal Khan solves a word problem while explaining this distinction. [11:45]

This video solves the problem of how long of a runway an A380 needs. [5:29]

Using position-time graphs and number lines to find displacement and distance traveled. [5:01]

This lesson introduces the learner to the concepts of distance and displacement and explains how to differentiate between the two. It is 2 of 3 in the series titled "Introduction to Distance and Displacement."

This lesson should provided the learner with example problems on finding the distance and displacement of an object. It is 2 of 2 in the series titled "Practice Calculating Distance & Displacement."

This lesson demonstrates how to find the position of an object undergoing constant acceleration. It is 2 of 2 in the series titled "Calculating Position Under Constant Acceleration."
