Question

what is newtons third...
newtons third law of motion states that for every action, there is an equal and opposite reaction. it is also called the law of action-reaction.
an action force is a force acting in a specific direction. a reaction force is a force acting in the opposite direction as another force.
action-reaction forces act in pairs and are equal and opposite.
when a rocket is launched into space, the action force is the fuel and exhaust pushing downward out of the rocket, and the reaction force is the rocket being propelled upward into space.
choose the correct answer
when a space shuttle launches, an action force and a reaction force occur. what is the action force?
the burning gases coming out from the bottom of the shuttle engines
the shuttle is pushed higher and higher towards space
the clouds moving away from the shuttle as it launches

Explanation:

To determine the action force when a space shuttle launches, we refer to Newton's Third Law (action - reaction pairs) and the example of a rocket launch. The action force is the force that initiates the interaction, and in rocket/space shuttle launches, the fuel and exhaust (burning gases) pushing downward out of the engines is the action force. The shuttle being pushed upward is the reaction force, and clouds moving away is not a force related to the action - reaction of the shuttle's propulsion. So the correct option is the one about the burning gases coming out from the bottom of the shuttle engines.

Answer:

the burning gases coming out from the bottom of the shuttle engines
