Not just Plato, Aristoteles even more. He kept Mechanics for 2000 in the dark ages, by assuming that heavier objects fall faster than lighter objects in proportion to their weight. He argued that a 10-pound stone would fall 10 times faster than a 1-pound stone.
Continuous force is needed for continuous motion - without a force pushing it, a moving object would immediately stop.
In fact continuous force leads to continuous acceleration. A bit of mathematics would have helped.
