I really need help guys! Please answer with detail, will give brainliest. What is velocity?

Answers

Answer 1
A velocity is when it determines an accuracy on the acceleration of it’s rate in transitions from it’s movement.
Answer 2

Answer:

Velocity is defined as the rate of travel of an object, along with its direction. Velocity tells you how fast an object is moving as well as in what direction it is moving. It is similar to speed, except that it also adds direction. So, while speed is directionless, velocity is directional speed.
