Will someone weigh slightly less in a high-flying airplane that maintains a constant height above Earth?
Yes. Because the accelerstion due to gravity is slightly less. The force of gravity decreases as 1 / the square of the distance from the center of the Earth to the object (your person). Since acceleration of said object is the force on it per unit of its mass, the acceleration decreases also as 1/ square of the same distance.
How much do food carts on airplanes weigh?
A long time ago I was watching The Flight That Fought Back on the Discovery channel (which I'm watching again right now actually). And it got to a part that mentioned that they were going to use a food as a battering ram, and a guy says that the carts weigh around 400-500 pounds...So then later it came up in a conversation with my friend and he absolutely freaked out, and told me to quit pulling things out of my ***. And ever since then (which has been a few years) he says I BS about everything. Now unless I'm joking and obviously going over the top, I always tell things as I remember them (which has all except for once been correct I should mention). So anyway he thinks they weigh like 25 pounds max, and I would really love to clear my name lol...by the way I'm not afraid to admit that I always get a tear in my eye watching that show!
Do airplanes on Mars need bigger wings to fly?
Do airplanes on Mars need bigger wings to fly?Compared with on Earth? Absolutely. Or else fly a lot faster. Or weigh a lot less. It’s true that the airplane would weigh less on Mars due to the lower gravity, but the density of the atmosphere is so much smaller than on Earth (about a factor of 100 at sea level) that you’d still need quite large wings. Still, it should be possible to design a plane to fly in Mars. It could use electric motors. Or rockets. We know that parachutes work. Aerodynamics is aerodynamics. We are building a helicopter to fly on Mars so we could also design an airplane to fly there. Actually, it would be easier to get an airplane to fly than a helicopter. But the take off and landing would be harder. No prepared runways. So we are starting off with a helicopter.
If Superman levitates inside a plane, would the plane weigh less than the combined weight of the plane and Superman?
That depends on the mechanism of his levitation. If it occurs based on producing an invisible force pushing against the airplane, like, say, in the case of magnetic levitation, then the airplane feels the same total weight regardless. On the other hand, if he is able to levitate based on no force exertion whatsoever, or by a repulsive force acting on some object other than the airplane without simultaneously affecting the plane in any manner, then the airplane would not feel Superman’s weight and they would be flying independently of each other, with Superman merely enclosed within the volume of the airplane body.
How many pound can i carry to the airplane?
i believe its 40, but im not positive. you can probly check out an airline website. you can take one carry on to split up the load.
Do we weigh more in an airplane due to our increased velocity?
No, we weigh less. As Tim Morgan pointed out, per the Lorentz transformation our mass would increase infinitesimally because of our relative velocity. However, weight is a property of both mass and gravity. As an airplane ascends, it is moving further and further away from the center of the Earth. And Gravity is inversely proportional to the square of the distance between two object’s centers. At a cruising altitude of 40,000 feet, I calculate a 1% weight loss!You can try the Math yourself ! Here’s the formula for weight (force). If you use the proper units (kgs, meters) you’ll get the answer in Newtons:Courtesy Wikipedia: Newton's law of universal gravitation
How much does fuel alone weigh in an aircraft?
Anywhere for 0% (gliders are airplanes...) to 83% for the Virgin Atlantic Global Flyer that went around the world (and then some) non-stop last year. Evidently, those are extreme cases, but still show what can of varaints needsot be taken into account. Is the airfraft a commenrcial airliner, and if so, a short range or a long range airplane? A commuter regional jet could have around 25 of its weight in fuel. For long range large ariplane, the A380 superjumbo would have 45% of its maximum takeoff weight in fule, if it takes up with maximum fuel. The Concorde (no longer in service) was considered a gas guzzler, with nearly 52% of its maximum takeoff weight made of fuel.
