Question

once out in space, the space shuttle needs to __ to keep going in the same direction at the same speed

Answer 1

answer choices:

A) turn off its engines
B) continue to fire its engines
C) fire its engines intermittently
D) gradually slow the engines down

Answer 2

recall Newton's First Law. once the shuttle is in space, it will keep going at the same speed and direction because there's no air resistance acting upon it to slow it down. therefore, it needs to turn off the engine to keep the force, and therefore acceleration, constant.
