an elephant will slow a rocket down
the weight of the rocket
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
Thrust - is the force pushing it forwards Drag - the force acting against the rocket Gravity - the force acting upon the rocket trying to push it towards the centre of the earth
thrust
Water rockets need fins because the rocket needs to stay in balance....without fins on a water rocket, the water rocket would be going out of control because it is not in balance!

Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
As a rocket burns fuel, it expels exhaust gases. When the gases are forced out of the rocket, they exert an equal and opposite force on the rocket. A rocket can rise into the air because the gases it expels with a downward force exert an equal but opposite force on the rocket. As long as this upward pushing force, called thrust, is greater than the downward pull of gravity, there is a net force in the upward direction. As a result, the rocket accelerates upwards.-information from Prentice Hall, Science Explorer: Physical Science

The force of the thrusters pushes the rocket upward, beating the force of gravity.
