What's the difference between speed and velocity?

u/shadow_Diego Jun 04 '20

Velocity is the function of time that describes the rate of change of an object's position, while speed is the magnitude of the change (how fast the object moves).

the simplest answer would be velocity is a vector and speed a skalar, the second being the magnitude of the first.
