Question

Explain scalar vs vector quantities in terms of speed, velocity, distance, and displacement. Making sure to explain each of these terms using specific examples

Answer 1

Speed - it is a scalar quantity for telling speed we don’t need to tell about direction it is just a magnitudeif partical is moving in a circle then for one circle average speed is non zero while average velocity for one circle motion is zero because displacement is zero..

velocity - it is a vector quantity for telling velocity we must tell direction as well magnitude of velocity, average velocity may be positive negative or zero while average speed will always be non negative.

displacement - it is a vector quantity depends only on initial position and final position of object.

distance - it is the length of path travelled by object in given time direction is not necessary.
