Newton`s 2nd Law
... A rocket becomes progressively easier to accelerate as it travels through space. Why is this so? (Hint: About 90% of the mass of a newly launched rocket is fuel.) ⇒ From Newton’s 2nd law, a = Fnet/m. As fuel is burned, the mass of the rocket becomes less. As the mass decreases, the acceleration incr ...
