Are you asking why the missions were performed (exploration) or why rockets move (every action is balanced by an equal and opposite reaction)?
The Saturn V (pronounced "Saturn Five") multistage rocket was used for all Apollo launches.
The first manned space shuttle mission occurred on the 12th of April 1981. However it was the space shuttle Columbia, not the Saturn V rocket. The Saturn V rocket was first used for a manned mission on December the 21st 1968. Two very different space vehicles. The Saturn V rocket was used to send man to the Moon, where as the space shuttle is used to sent humans into Earth orbit.

The type of rocket that launced Apollo 11 into space is the same type of rocket that was used for all Apollo launchings. The Saturn V (five) multistage rocket was used.

The Saturn V used in the Apollo missions.
The success of the Saturn V rocket was largely due to its design under the direction of Wernher von Braun and Arthur Rudolph, German rocket scientists, who previous created the V-2 rocket. The Saturn V and Mercury-Redstone rocket programs were competing to make the trip to the Moon and the Saturn V rocket ultimately won.
It's not, very much, except in the sense that both of them have a booster stage that doesn't go into orbit and a payload section that does.
