  1. Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

  2. Distance is a scalar measure of the interval between two locations measured along the actual path connecting them. Displacement is a vector measure of the interval between two locations measured along the shortest path connecting them.

  3. Learn the key concepts, equations, and common misconceptions related to distance and displacement in physics. See examples, graphs, and exercises to test your understanding.

  4. Learn how to describe motion in different reference frames and distinguish between distance and displacement. Explore the concepts of position, magnitude, vector, and scalar with examples and activities.

  5. Learn the difference between displacement and distance in physics, and how to calculate them using equations and examples. Displacement is the change in position of an object, while distance is the size of the displacement or the total length of the path traveled.

  6. Learn the difference between distance and displacement, two quantities that measure the movement of an object. Distance is the total length of the path, while displacement is the change in position with direction.
