if birds are caged on a plane and they all fly in flight do they weigh anything?

Question

if you jump up and down on a moving train do you land on the same spot you started from

Answer 1

1. (Birds) Yes. A bird flies because its wings push air downward. That moving air hits the floor of the airplane's fuselage and causes just as much weight to the airplane as if the bird had been sitting.

2. (Train). You land at the same spot with respect to the train, but at a different spot with respect to the ground.

Answer 2

Gravity continues to have an effect whether flying in a plane or flying in open air. Same goes for the train. Because gravity holds you to the train you are moving with the train, you land in the same spot on the train because you are traveling the same speed as the train but the train is in a different spot on the track. If you jump off the train, gravity pulls you to the ground and friction slows you down, but in the train friction is excerted on the train.

Answer 3

Yes, the bird have weight. If you jumped straight up and down on a train, you would land in the same spot in the train, but a different spot on the track.

Answer 4

The weight is the gravitational pull by the earth. Whether the birds are sitting or flying the force will be pulling it down; if they are flying, it means by the movement of the wings they create a force which makes them move against the force of pulling down.

When you are moving in a train or any vehicle, you are also moving with the train.

If the train moves with a speed of 30m/s toward east, you and all objects in the train are moving with 30 m /s.

When you jump up in the train, you are moving with 30m/ s toward east and also you are going up. When you come down also, you are moving with 30m/ s toward east. Therefore you reach the same pint in the train.

If you are jumping up to a very great height, then you are not in contact with the train for a long time. Therefore your speed toward east will decrease, whereas the train will be moving toward east with 30m/s. In that case, you will reach a spot behind the spot from which you jumped.

Answer 5

A bird will always weigh the same, but if the plane was completely full of birds and they all flew, would the plane weigh less???????
As for the train conundrum, there is no wind Resistance, to make you move, so you will stay in the same spot!!

Answer 6

hi Andrew, best suited Q. Your previous solutions putting ahead that the down-rigidity of the birds may equate to their raise ingredient, and so stability out, are fantastic & sound, yet no longer pondering forwards or backwards action. yet another issue ? actual a ingredient, yet it truly is an exciting similar set of circumstances. a set individuals contained in the decrease back of a C130 Herc , no seats, strap-putting contained in the Mid East were requested by technique of the loady sergeant to all bounce up on take-off, because the airplane became "somewhat too heavy to sparkling the fence at the different end of the strip". I watched in leisure and amazement as a dozen blokes did so. ought to of placed it to music ! for sure all of us crashed into the sea as one hundred and fifty stone of bods arrived decrease back on the floor. (no longer). in words of organic physics, because the equations bypass - F+I2 = F-12 (-a million + the loady) Heh Ho ! Bob.

Answer 7

If you jump off the top of a falling rock just before it hits the ground, you are going slower than the rock, but you still go splat!

Answer 8

If the train is at constant speed yes. If the train is accelarating no.

Answer 9

Applechick 282 is right.

Answer 10

yes nomaybe
