There’s two things here, big things do move faster. Horses run faster than insects..
But they don’t accelerate as fast.
There’s a thing called the cube square law that relates lots of things but size and weight are the important one here.
If you double the size of the creature, it’s weight goes up way more than double.
If it grows from one cubic inch to 2:
Size 2×2 is 4
Weight 2x2x2 which is 8
If it grows to 5 cubic inches
Size 5×5 is 25
Weight 5x5x5 which is 125
Bigger sizes even bigger weight increases. Eventually the inertia of the animals body makes super fast acceleration impossible
