Final answer:
The statement about a rocket's movement in space is true, aligning with Newton's first law of motion, which contributes to our understanding of space exploration and rocket dynamics.
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. According to Newton's first law of motion, also known as the law of inertia, an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force.
Once a rocket reaches space and is no longer under the influence of Earth's gravity or any other significant force, it will continue on its trajectory due to inertia. This concept is fundamental in space exploration and understanding rocket dynamics.
