Question

what is the purpose of solving the speed and velocity of an object​

Answer 1

Answer:

What's the difference between two identical objects traveling at different speeds? Nearly everyone knows that the one moving faster (the one with the greater speed) will go farther than the one moving slower in the same amount of time. Either that or they'll tell you that the one moving faster will get where it's going sooner than the slower one. Whatever speed is, it involves both distance and time. "Faster" means either "farther" (greater distance) or "sooner" (less time).

Speed is directly proportional to distance when time is constant: v ∝ s (t constant)

Speed is inversely proportional to time when distance is constant: v ∝

t

(s constant)

velocity

In order to calculate the speed of an object we need to know how far it's gone and how long it took to get there.

Average speed is the rate of change of distance with time.

Average velocity is the rate of change of displacement with time.
