The space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.
The force of gravity pulls every towards the center of the Earth, to overcome this force of gravity the space shuttle will create an upward force that is greater than force of gravity.
The upward force created by the space shuttle engine must overcome the downward force of gravity on the space shuttle.
To overcome the force of gravity, the space shuttle engine speeds upwards with a velocity known as escape velocity.
Thus, we can conclude that the space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.
