You don't. Constant means it doesn't change at all.
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
change in acceleration
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
Tine 🍴🍴
The metal tines can be moved in or out to change their pitches. To change the scale or pitch of any note simply tap the tine in or out with a mallet. Tapping at the back of the tine will lower the pitch, tapping the front will raise the pitch.
A projecting point or prong of a fork is called a tine.
A value that does not change is a constant.

You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
