OK to my knowledge everything moves by using friction,or pushing off of something but how would say a spaceship move, i know that I am over looking somthing very obvious but I am just not sure what it is.

Or have you and your friend on roller skates, and push off him/her. You will find that you both move in opposite directions. It will not make much difference how far you travel if you coat your hands in vaseline or with sandpaper gloves.ZapperZ said:Hold a ball while standing on skates on ice.

In order for a spaceship to move in outer space, it must use a propulsion system. This can include rockets, ion thrusters, or solar sails. These systems generate thrust, which propels the spaceship forward.
Fuel is a substance that is burned to produce energy, while propellant is the substance that is ejected from a spacecraft to create thrust. In most cases, fuel is used to power the propellant, which then creates the thrust needed for space travel.
Rockets work by following Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In a rocket, fuel is ignited and expelled out of the back of the rocket, creating a force in the opposite direction and propelling the rocket forward.
No, spaceships cannot move without some form of propellant. Even if a spaceship is using solar sails, it still needs some form of energy to power the sails and propel the spacecraft forward.
The speed of a spaceship depends on the type of propulsion system it is using and the distance it is traveling. For example, rockets can reach speeds of up to 25,000 miles per hour, while ion thrusters can reach speeds of over 100,000 miles per hour. However, due to the vast distances in space, it can still take years for a spaceship to reach its destination.
