Displacement (article) | Kinematics | Khan Academy
This equation says that displacement is the change in an object's position, or equivalently, the difference between the object's final position and initial position.
Distance and displacement introduction (video) | Khan Academy
Your displacement is your change in position and since it's a change in position, not only will we mention the five kilometers, we'll say in what direction. The position of the sheep has changed …

What is velocity? (article) | Khan Academy
Your notion of velocity is probably similar to its scientific definition. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of …
Intro to vectors and scalars (video) | Khan Academy
Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. …
Angular motion variables (video) | Khan Academy
So recapping, the angular displacement represents the angle through which an object is rotated. It's typically measured in radians, and it's represented with a delta theta.
Distance and displacement review (article) | Khan Academy
People sometimes think that distance and displacement are just different names for the same quantity. However, distance and displacement are different concepts. If an object changes …
Definition of amplitude and period (video) | Khan Academy
By definition, displacement is final position - initial position (relative to a point) - As the final position and the initial position is the same, if the mass completed exactly one whole cycle, its …
What is acceleration? (article) | Khan Academy
What does acceleration mean? Compared to displacement and velocity, acceleration is like the angry, fire-breathing dragon of motion variables. It can be violent; some people are scared of …
Spring force and Hooke's law (article) | Khan Academy
If we graph the force (F) and displacement (X) of two different springs on x, y dimension and the graphs cross each other at a certain point, is that mean that both springs has the same …
