There are several different technologies that fall into the "catapult" category. They include the catapult, the ballista and the trebuchet. The catapult is the winched-down bucket that people normally think about when they hear the word "catapult" (see this page for a picture). A ballista is a very large crossbow (see this page for a picture). A trebuchet is a weighted beam that swings a sling carrying the projectile (see this page for pictures).

Both catapults and ballistas work by storing tension either in twisted ropes or in a flexed piece of wood (in the same way an archery bow does, but on a larger scale).

A trebuchet tends to be easier to build because it consists simply of a pivoting beam and a counterweight that rotates the beam through an arc.

Catapults can launch things a fair distance -- 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time. Then all of the energy releases at once, throwing the projectile.

Answer 2

try the old see saw trick (but the thing your going to launch is going to have to weigh less then what you'll drop on the other side which is your cointer weight or you can have the counter weight held up in the air and the launch victum on the other side and the counter wieght is to only be held up by a strring that is easy to cut and when you cut it the coutner weight will drop laughing the victum

Use a small plastic spoon, bend back, place projectile, let go.
