How can the three laws of motion affect a rocket while it is in the air?

OK so im a freshman and i need help on this... how can the three laws of motion by sir isaad newton affect a hand-built rocket??? if i could jus have some kind of info on this it would be much appreciated...How can the three laws of motion affect a rocket while it is in the air?I don't remember the exact order these belong in, but here goes:

1) For every action, there is an equal and opposite reaction.

2)Objects in motion tend to stay in motion.

3) An object at rest, tends to stay at rest.



What this means, is that the rocket is being held to the ground by gravity, and will want to stay put. To begin it's motion, you'll need to use an amount of thrust that's opposite, and a little more than equal gravity. Once it's in the air, it won't need quite as much push because it's momentum has already started, so as long as the thrust is equal to gravity, the rocket will continue it's ascent.How can the three laws of motion affect a rocket while it is in the air?I don't know but keep trying you'll figure it out.How can the three laws of motion affect a rocket while it is in the air?1. the air around it slows it down

2. gravity pulls it down / slows it down.

3. momentum pushes it forwardHow can the three laws of motion affect a rocket while it is in the air?
Well 1st while its in the air the 3rd law may not be affective cause it can't really push on air and 1st law can affect it if an object comes in the way out of no where. and the 2nd its the same.



SO what I'm tryin to say is that any of the three laws are possible to happen to the rocket while in the air.

remember that it can be hard for the 3rd law to take place while in the air.
