Throw an object into the air. Gravity will create an acceleration of -9.81 m/s^2, slowing the object down.

Constantly.
Actually you'll find that it's easier to use gravity to change the acceleration of an object, and then solve for the velocity.
Hope that helps,
Matt

I think maybe you have heard of what is called the "slingshot manoeuvre", where a space ship uses the gravity of a planet to reach deeper into space. In such a case, as a space ship approaches a planet it is accelerated towards it, and as long as the ship is travelling in the same direction as the planet, and as long as it doesn't fall onto the planet, it will shoot past the planet and hurtle into space with a greater velocity, but in a slightly (or perhaps greatly) different direction. This phenomenon is used to send probes to the outer planets and saves on fuel.

You just let it fall.
