Question

Define acceleration and velocity?

Answer 1

Velocity is the rate of motion in a specific direction. I'm going that-a-way at 30 kilometers per hour. My velocityis 30 kilometers per hour that-a-way. Average speed is described as a measure of distance divided by time.Velocity can be constant, or it can change (acceleration)

acceleration is a rate of change of velocity.....

Answer 2

acceleration is the rate of change of velocity with time
velocity is the distance travelled per second by the body in a specified direction
