Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
By changing direction. Acceleration is a change in velocity. Since velocity takes direction into account, while speed does not, an object can having a changing velocity even while its speed remains the same. And while that object is changing its velocity by changing its direction, it is accelerating, regardless of its speed remaining constant. For example, if a car is driving north at constant speed of 20mph, its speed is 20mph, while its velocity is 20mph towards the north. At this point, the car is not accelerating. Now if the car turns a corner to head east while maintaining its speed of 20mph, its velocity is changing from 20mph northward to 20mph north-eastward and finally to 20mph eastward. As it is turning, it is accelerating. However, as soon as it stops turning, the car is no longer accelerating.
Could be wheel balance.
Thinking my car needs a tuneup its jerking and lunging over speeds of 20mph
koalas aren't bears so It's most likely giant pandas which can run at max speeds of 32kph (20mph)
Check your air intake, maybe your car cant get enouhg air at lower revs due to a blockage in the airintake?
20mph
could be u-joints or transfer case. gm Jim

Final velocity minus starting velocity, divided by time it took. Ex. Speeding up you car from 40mph to 60 mph when going on to freeway. It took 2 seconds. 60mph - 20mph= 40mph/2sec =20mph 20mph is your acceleration.
In California, mopeds are classified whether they are capable of speeds exceeding 30mph or 20mph. The faster mopeds require a M1 or M2 license. The slower mopeds do not require a license but have other financial requirements.
