A machine that uses escaping gas to move.
A
rocket
B
asteroid
C
probe
D
None of the above
Explanation: 

Detailed explanation-1: -Rocket engines use the pressure of expanding gas to generate thrust. Newton’s third law explains why rockets move in a direction opposite to the direction of the escaping gas.

Detailed explanation-2: -Spacecraft can also orbit the Earth. If an object gains enough speed to attain escape velocity, its orbit becomes an open curve called a parabola.

Detailed explanation-3: -Thrust is the force which moves the rocket through the air, and through space. Thrust is generated by the propulsion system of the rocket through the application of Newton’s third law of motion; For every action there is an equal and opposite re-action.
