Question

What is velocity? Explain it! Formulae too✌️​

Answer 1

Answer:

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.

Answer 2

The terms velocity and speed give us an idea of how fast or slow an object is moving. Quite often, we come across situations where we need to identify which of the two or more objects is moving faster. One can easily tell the fastest of the two if they are moving in the same direction on the same road. But if their direction of motion is in the opposite direction, then it is difficult to determine the fastest. In such cases, the concept of velocity is helpful, which we shall be discussing in this article.

Unit of velocity

Common symbols v, v, v⃗

SI unit m/s

Other units mph, ft/s

Dimension LT−1

Average velocity, v = △x△t
