The Law of Action and Reaction: Newton's Third Law

This NASA video segment explores how Newton's third law of motion applies to aerospace. An instructor at NASA's National Test Pilot School defines the third law and explains how a jet engine works to move an aircraft forward. There is also a discussion about the four forces involved in flying an aircraft.

@renzopogie Cool. Newton's 1st and 2nd Law being applied in harmony.

[renzopogie]

@batthatisbat yeah you mean constant motion.... a body at motion will remain in motion unless there is an outside force and since the drag and thrust are equal, it will still remain in motion and it will acclerate and decelerate when the force is not equal. Therefore, the force bigger than the other one becomes the outside for acting on the airplane...

@renzopogie Newton's Second Law. Force = mass x acceleration. No force = no acceleration, which means the speed/velocity isn't changing, but that doesn't mean there *is* no speed/velocity (it's just that it's not changing). Hope that helps!

@batthatisbat yeah you're right im also confused haha

Question students might ask after seeing this is how the plane can move forward if thrust and drag are equal.
