Detailed explanation-1: -Space ships do not stop when they run out of fuel. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.
Detailed explanation-2: -Newton’s Third Law: For every force there is a reaction force that is equal in size, but opposite in direction. For example: when the space shuttle takes off, the fuel exhaust pushes downward against the launch pad while the reaction to that force pushes the rocket upward into the sky.
Detailed explanation-3: -At liftoff, the two Solid Rocket Boosters consume 11, 000 pounds of fuel per second. That’s two million times the rate at which fuel is burned by the average family car. The twin Solid Rocket Boosters generate a combined thrust of 5.3 million pounds.
