When velocity is constant What is acceleration?

If a body is in LINEAR MOTION , and if velocity is constant , acceleration is zero , because acceleration is rate of change of velocity ! We need a change in velocity to calculate acceleration . Since it is constant , no change in velocity , no acceleration . Therefore acceleration is said to be zero .Click to see full answer. Then, what does constant velocity mean in terms of acceleration? Constant Acceleration vs. Traveling with a constant velocity means you’re going at the same speed in the same direction continuously. If you have a constant velocity, this means you have zero acceleration. The velocity starts low, but increases by 9.8 m/s for every second it is falling under gravity.Additionally, can acceleration change if velocity is constant? An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. In respect to this, when acceleration is constant what happens to velocity? In the middle, when the object was changing position at a constant velocity, the acceleration was 0. This is because the object is no longer changing its velocity and is moving at a constant rate. Towards the end of the motion, the object slows down.What is velocity formula?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. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
