What is the interaction that occurs when a rocket lifts off?

The correct interaction that occurs when a rocket lifts off is between the rocket and the exhaust gases. This interaction is explained by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

When the rocket engines ignite, they expel exhaust gases downward at high speed. This action creates a force that propels the rocket upward as a reaction. The rocket's engines push against the gases, and the gases push back against the rocket with an equal force, enabling the rocket to lift off the ground. This principle is essential in understanding how rockets operate in space and throughout the atmosphere.

While interactions with the launch pad, air pressure, and fuel are involved in the overall process of launching a rocket, they do not directly represent the primary mechanism that results in the lift-off. The force must be generated from the expulsion of exhaust gases to overcome the weight of the rocket and achieve flight.
