Question

the motion of rocket depend upon which principle and why?​

Answer 1

Answer:

In rocket propulsion, matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains.

Explanation:

Key Points

• The propulsion of all rockets is explained by the same physical principle: Newton’s third law of motion.
• A rocket’s acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket.
• To achieve the high speeds needed to hop continents, obtain orbit, or escape Earth’s gravity altogether, the mass of the rocket other than fuel must be as small as possible.

Key Terms

Newton’s third law of motion: states that all forces exist in pairs: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal and opposite: FA = −FB.

Answer 2

Answer:

motion of rocket depends upon the Newton's third law which means for every action there is a equal and opposite reaction
