Question

what is mean by velocity and acceleration​

Answer 1

Answer:

Velocity is speed with a direction, so distance over time with a specific direction. And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes. Whether you are speeding up, slowing down, or changing directions, you are changing your velocity and thus, accelerating.

Answer 2

Answer:

Acceleration. Meaning. It alludes to the speed of an object in the given direction. Acceleration implies to any change in the velocity of an object with respect to time.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
