Constant acceleration indicates that there is no change in acceleration. The slope of the linear curve in the velocity -time graph gives the constant acceleration.
Acceleration is a physical quantity which measures the rate of change in velocity. Acceleration is a vector quantity thus, having both magnitude and acceleration.
Acceleration is mathematically the ratio of change in velocity to the change in time. Thus, if we plot the velocity with different times, we can determine the acceleration from the graph.
If the velocity - time graph gives a linear curve indicating the change in velocity is directly proportional to the change in time and the acceleration is constant. The slope of the straight line, gives the constant acceleration.
