What is the difference between speed and velocity? a. velocity takes acceleration into account, while speed does not. b. speed takes acceleration into account, while velocity does not. c. velocity is an expression of displacement per unit time, while speed is an expression of distance per unit time. d. speed is an expression of displacement per unit time, while velocity is an expression of distance per unit time.

C!

V= displacement/time
Speed= distance/time

Displacement is the space between two points, usually from the first to last point, but doesn't have to be. (Basically, it's the distance between your starting and ending point). With displacement, direction matters, but with speed, direction doesn't.

Speed, on the other hand, is the entire traveled distance as a whole. Unlike displacement, direction doesn't matter.

I hope this helped!

picture isn't rlly clear :/
