Question

1. how does newtons third law explain how a rocket takes off?*

the rockets acceleration is positive, while the gasses acceleration is negative but the direction is the same.
the rocket is at rest until ignition.
gravity of space pulls rocket up
the hot gasses move in one direction, while the rocket moves in the opposite direction but with equ! force.

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. When a rocket expels hot gases downward (action), the gases exert an equal and opposite force on the rocket, pushing it upward (reaction).

• The first option is incorrect because acceleration directions are opposite, not the same.
• The second option refers to Newton's first law (an object at rest stays at rest until acted upon by a force).
• The third option is incorrect as space has microgravity and it's the rocket's engine thrust (based on Newton's third law) that causes lift - off, not space gravity pulling.

Answer:

the hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.
