Momentum. There's very little force acting on it to slow it down. The main force to slow it would be the gravity of the sun and the moon.

The iron core of the earth rotates and creates a magnetic field. This in turn continues the rotation and keeps it at a steady rate.
The moon acts as a slow but steady brake to gradually slow down the rotation. That is why the years get longer by a few seconds every year. Over time that translates into longer days as well.
This can actually be calculated to each tiny bit of the extra time within each second (a very small amount to say the least.)

You have to put away your Earthly experiences when thinking about space. On Earth, every motion you know of is slowed down by friction (rubbing), even if that is simply the air resistance.
Take your foot off the gas in your car, and you are slowed down by air resistance, friction between tires and road, and friction in the wheels, bearings, engine, etc etc
In space there is no friction. That is why it is dangerous space-walking. If the astronaut pushed off from the ship, just a slight push, and his tether broke, he would drift off forever.
