Homework Statement In a flying ski jump, the skier acquires a speed of 110 km/h by racing down a steep hill and then lifts off into the air from a horizontal ramp. Beyond this ramp, the ground slopes downward at an angle of 45 degrees. (a) Assuming the skier is in a free-fall motion after he...

Hi, a friend of mine - a college physics professor, and me, have had a discussion about an experience he had in his early school days, and we haven't been able to prove or dissprove what he thinks he saw. During an incandescent light burn-out (12V bulb on 220V =), he thinks he might have...

Sorry i didn't know where else to ask this so I'm hoping you guys can help anyways. If a air moving over a wing causes lift then why do planes need to move in order for this to happen. What i mean is instead of moving in order for the air to pass the wing why can't we "blow" air at fast speeds...

Hey, I was just referred to Physics Forums by a friend. I am not sure if this is in the correct forum, please movie if necessary. I just received a project for my High School Physics I class. I have to create a Flying Shoebox Cargo Project. This is the rubric...

Hi there, I was just wondering if it would be possible to create a hover board by using sound. i have a vague idea on how it would work but would it be feasible or just a waste of time and effort or even if there are some out there already. It would work by using some speakers and a...

This is part of a project I'm doing, and I'm not sure if you can actually work out the answer with the information I have available, but I'll see. Its a review of the physics involved of the scene in the monty pythons the hold grail where the cow is catapulted out of the castle. So, the question...

This isn't purely an Earth science question, but I don't know where else to post it. Recently, the Kasatochi volcano erupted in Alaska. It brought to mind something that happened to me a long time ago that I have always wondered about. In 1989 I was flying from Alaska to Seattle. Days...

Why is a space probe spinning around its own axes, when flying through space?

Hi, My name is david and i was wondering if you would be able to see if my theory works. I don't know anything about physics but i do have a good inventive imagination. I want to know if you had 8-10 air compressors at maximum pressure and a 7m hose and nozzle fore each compressor attached...

I'm working on a project with several others to create a flying device much like a blimp, but smaller and more agile. Our method of life is eighther a light gas like helium or preferablly, a Vacuum system that ajusts the % of vacuum inside a set space to provide lift and control decent. The...

Can anyone explain how flying ring works? like the demostration whith a magnetic coil connected to AC poer and an aluminum ring. the ring was placed on the top of the coil and althought aluminum is a non magnetic, the ring was thrown to the ceiling. can anyone tell me why there was force on...

Homework Statement Place a pencil on the edge of a table and I hit it. How shall it fly? When will it fly the highest distance? Homework Equations Definetely F=m*a and for the flight x = 1/2 a t^2 The Attempt at a Solution Well there are several hidden factors that are making the...

Well we know guys that the Earth spins to the east. So i was thinking, if you launch projectiles (lets say golf balls) of equal speed and angle to the east and launch some to the west, will the ones thrown to the east land farther from the launching point compared to the ones thrown to the west...

Question is: plane flies at a speed of 100m/s at a height of 18m above water plot the trajectory from release to first impact point, in intervals of 0.2m managed this and have plotted the trajectory, with relevant velocities and resultant but the next part asks: "At each bounce the...

just seen this flying rods on tv and people almost everywhere have seen and captured it on film just wondering if its real or something. here are some links if you don't know what iam talking about. http://www.subversiveelement.com/Rods.html

I once read an article that said the average weight of a cloud is equal to eight elephants. I know that they are very massive and even larger so they are not that dense knowing this I pose two questions... How would one measure the wieght of a cloud when the density/volume is not uniform nor is...

I know this may seem elementary to many on this forum so please forgive me if it does. We are having a late Christmas celebration and this question has arisen. If a fly is in a plane and flying does the plane weigh more than before the fly entered the plane? Assume the fly continues to...

It is known that maximum braking occurs when the front brake is applied so hard that the rear wheel is just about to lift off. Skilled cyclists use the front brake alone probably 95% of the time. However, improperly modulating the force applied on the front brake will bring the bike to a...

We have bees flying in a jar, not touching it. Jar is closed and air in it has standard atmospheric pressure. Here is the question: if we put that jar on a weighing-machine, is ti going to show the mass of the bees? I had some theories about it, but many people thought differently, trying to...

A truck driver, it is said, once explained that when he was crossing a bridge and was overweight with birds; he just rapped on the truck and got the birds flying, so the truck was lighter! Of course, it was explained on MythBusters that Newton's Third Law does not work that way; and by...

Hi I've got a question concerning a previous question I've done. A person is holding a toy airplane which flys in the air with a constant radius. is the lift force the same as reaction force? is it equal to the vertical component of the centripetal force and weight force of the airplane?
