Hmm, okay. The question is: What is the difference between 'Velocity' and 'Speed'? I've been trying to understand it but I couldn't get to a resolution. Is there anyone out there willing to help me with this problem of mine? I'd really appreciate it. Bye now!

Velocity is the rate of change of displacement while speed is the rate of change of distance. In case you did not know displacement is the direct distance between two points. Distance on the other hand is the total and distance traveled, not measured by two points but literally just distance. This means that velocity is a vector while speed is not a vector. Velocity is preferred to be used in calculations like forces and etc because it is definitely accurate to take directions or vectors into consideration when involving forces and etc. In daily life speed is used in cars to measure actual acceleration and distance travel per second. It is absurd to use velocity for cars' speed due to some roads might have curves and slopes and if velocity is used the data ought to be incorrect if to measure a car's performance.
