B.) Action and reaction forces helps during lift off of a rocket.

Hope this helps!

Answer 2

Answer:

B. Action and reaction forces

Explanation:

Newton's third law of motion, which states that action and reaction forces are equal and opposite, makes a rocket achieve lift off.

When the engine of a rocket burns fuel, the rocket experiences a thrust (a push) on the front that pushes it upwards. This thrust causes an equal and opposite push on the exhaust gas of the rocket downwards. The burning of the fuel is the action, the thrust, and it causes the rocket to move upwards. The push back on the exhaust gas is the reaction caused by the weight of the rocket.

For the rocket to lift off, the thrust must be greater than the weight of the rocket.
