A rocket leaves a launch pad at liftoff with a great deal of upward momentum. What was initially given

downward momentum?
a. the launch pad
b. the astronauts aboard the rocket
c. the expelled fuel
d. the entire Earth

Entire esrth

Launch pad

The entire earth

launch pad

The correct answer is c. the expelled fuel. When a rocket is launched, it expels fuel in the form of exhaust gases at high speeds. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In the case of the rocket, the action is the expulsion of the fuel, creating a force pushing it in one direction. This force generates a reaction force in the opposite direction, which is the upward momentum of the rocket. As a result, the expelled fuel gains downward momentum. Therefore, the initially given downward momentum in this scenario is the expelled fuel.
