Yes. An oscillation does it with finite mass and energy The acceleration is
limited, which is another way to say that it is continuous.
In a discrete computing system a huge number of states are "equidistant".
You pay the same "price" for incrementing a register by one and for
resetting the CPU. This allows you to make great things - you can "travel"
to anywhere you want in very few steps - but this also makes the trajectory
so unpredictable.
