Q.16.
How does Newton’s third law explain how a rocket takes off?
The rocket’s acceleration is positive, while the gasses acceleration is negative but the direction is the same.
The rocket is at rest until ignition.
The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.
