Final answer:
The statement is true. When a rocket escapes Earth's gravitational pull, it will continue to travel in a straight line until acted upon by another force.
Step-by-step explanation:
The statement, "A rocket is launched into space and escapes Earth's gravitational pull. It will continue to travel in a straight line until it is acted on by another force." is True.
When a rocket is launched into space and escapes Earth's gravitational pull, it enters into the vacuum of space where there is no air resistance or other forces acting on it. According to Newton's first law of motion, an object in motion will remain in motion in a straight line, at a constant speed, unless acted on by another force. Since there are no forces in space to change the rocket's path, it will continue to travel in a straight line until it is influenced by another force, such as gravity from another celestial body or thrusters on the rocket itself.
