Acceleration is the time rate of change of velocity. If velocity is constant, then. acceleration is zero. Note: 100 km per h for 10 seconds is a constant speed, but not necessarily a constant. velocity, since we're told nothing about the direction.
The slope on the velocity vs time graph equals the acceleration. Let's change the situation again. Instead of the car traveling at a constant acceleration suppose its acceleration changes by 1 m/s 2 every second. This is a constant jerk of 1 m/s 3.
