The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

Question

why is it possible for a rocket to travel in space? Which of Newton's laws of motion explain an accelerating rocket?

Expert Solution

Step 1

In space, the motion of rocket does not required air to push. The motion of rocket is depends on the Newton’s third law. Rocket and engine will give equal and opposite force on each other. This reaction force given by the engine will help rocket to move forward direction.
