This is a simple physics tutorial aimed at high school students in grades 9 and 10 (GCSE, HSC) answering the common questions:
- what is distance?
- what is displacement?
- how do distance and displacement differ or compare.
This tutorial is a follow on from one reviewing scalar and vector measurements ([ Ссылка ]). Distance and displacement are similar in that they both describe a magnitude of ground covered. They differ in that distance measures the actual traversed space between the the origin and destination, whereas displacement only takes into account the shortest, most direct route between the two.
They also vary in that distance does not consider direction, where as displacement does. This is because displacement is a vector measurement, whereas distance is a scalar measurement.
The video goes through three examples, and demonstrates how distance and displacement are measured, and how they compare. The last example reviews the distance and the displacement of the earth after one orbit around the sun. This example demonstrates that if the origin and the destination are the same, the displacement will be zero.
