How does Isacc Newton's 1st, 2nd and 3rd laws of motion apply to rocket flight?

Answer 1

Hey, right on, White Stallion! But I'll cover for you now.

1) A small meteor in outer space will continue in its motion uniformly until stopped by a rocket craft.

3) During stage separation facilitated with explosive bolts, the action of rejection of a spent stage is matched by the reaction of the upper stage continuing its flight.

2) The acceleration experienced by either the spent stage or the continuing stage is dependent on each of their masses, computed as follows:

F = m1 a1 = m2 a2

where F is the force produced by the explosive botls.

Answer 2

You don't have to be a rocket scientist to understand rocket science! d(^_^)b

1st Law: a body in motion will remain in motion, and a body at rest will remain at rest unless an unbalanced force acts upon it.

If your rocket accelerates to 200mph and then shuts off its engines, it will keep moving in a straight line at 200mph FOREVER, or until it smacks into something or fires another rocket to make itself speed up, slow down, or turn.

2nd Law: A constant force will cause the object to accelerate at a constant rate.

A rocketship can be using up a constant amount of fuel-- let's say 350 newtons of force every second. Now, it is not going to go at a constant speed-- it is going to be ACCELERATING. You have your rocket engines going at, uhh, 4,000 newtons of force. You use up 2 gallons of gas every minute. The ship isn't going to be going at 200mph at 3:30 and still be going at 200mph at 3:45, 4:30, and 6:00. It's going to be going 200mph at 3:30, 400mph at 4:30, 1600mph at 5:30, etc. (my math is COMPLETELY off here.) In fact, eventually, with just that small amount of constant force, given enough time, your rocket ship will reach the speed of light.

3rd Law: When Object A pushes on Object B, Object B is ALSO pushing on Object A with equal and opposite force.

When the rocket ship makes itself move, the propulsion... like, fuel being pushed out of it... pushes against the rocket with a certain amount of force, and the rocket pushes against the fuel stuff with an equal amount of force in the opposite direction. The rocket and the fuel residue it emitted fly away from each other at the same speed.

Answer 3

1 - A rocket may not injure a human being or, through inaction, allow a human being to come to harm.

2 - A rocket must obey orders given it by human beings except where such orders would conflict with the First Law.

A - rocket must protect its own existence as long as such protection does not conflict with the First or Second Law.

Oh, wait, those are Azimov's laws or robotics :-)

Answer 4

think of kicking a ball, the two ur kick is basically too feeble to no longer make the ball pass, or it ought to pass. attempt combating a shifting ball, probability is that in case you're utilising a great deal of attempt to stand as much as the action u might end it or the ball might proceed shifting. 1st regulation states that, physique with with consistent velocity or at relax will proceed in its stae of action (relax or shifting with consistent velocity) until acted upon by skill of a tension. 2d regulation. while u do kick the ball, that's going to pass. The tension u utilized, will reason it to alter its velocity. the fee of substitute of momentum of ball is without postpone proportional to the stress utilized and is often is a similar course because of the fact the stress. third regulation: while u do exert a tension on the ball, the ball exerts an equivalent yet opposite (reaction) tension ON you. as u exerted equivalent cost of action tension.
