How do you beat the pull of gravity to launch a rocket?

The same way you "beat the pull of gravity" to move yourself from the first floor

up to the second floor. You exert an upward force on your body greater than the

force that attracts the earth and your body toward each other, and the result is

that they separate. This can be accomplished using an escalator, elevator, winch-

line, staircase and leg muscles, etc.
