Answer 2

Answer:

hope it helps you

The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is meter per second (ms-1). If there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
