Model Rockets

Probably not, but I wouldn't recommend standing too close to the rocket as it lifts off. The fumes from the rocket's engine definitely aren't very good for your lungs.

it is spalding 29.5 inch official game ball . it is the official ball of the NBA,WNBA,and D - luege . college basketball teams use the Wilson NCAA .

Yes, they are the same diameter.

One of the goals of engineering is to save money and reduce cost. The bigger something is the more materials are needed and the more money it will cost. So that's why they're skinny. They're pointy because located at the tip is the launch abort system (LAS) which in case something goes wrong during launch, it can safely remove crew from vehicle. Hope this info. answers your question.

At high elevations, the force of gravity becomes less.

Keeps the engine inside the rocket when the ejection charge fires to prevent loss of pressure and failure to eject recovery system.

No. I'm sure you knew that, though. It is made of rock and iron oxides, and is covered in land marks such as hills, valleys, and volcanoes. Please don't ask a silly question next time, though. It is time wasting. Thanks.

Lift, drag, thrust, and gravity.

about one-forth of the height of the size of the rocket.

It depends on the motor. They are all rated in power and length of 'burn'

You need to use a type of motor that fires a 'retro' charge. Estes makes these in many sizes.

it works by burning flamable stuff inside it

With a good design and light tube, it will go 4-5,000 feet.

Conservation of momentum: The net momentum of the entire system (rocket plus propellant) is zero, so one is positive (this way) and one is negative (that way). If this way is up, then that way is down, or left and right, east and west, whatever way you want to look at it.

The rocket would be carrying extra dead weight and likely would not have enough fuel to reach its destination.

It isn't the size of the engine so much as the distance from the airport. You should not launch a model rocket anywhere within 15 miles of an airport. Larger rockets do, of course, pose a greater risk to aircraft, so if you are launching a G or higher engine, make sure you contact the nearest airport to verify that you are launching, and to keep planes clear of the area.

They usually have a shaped clay nozzle formed into the end of the engine tube. This differs slightly for the intended duration of the engine.

you have to glue bits and pieces together ;-)

Angle the fins so it spins, like a screwdriver

You would have to soften it in water then mold it around something and let it dry in place. Poster-board is not an easy thing to work with.

it first originated when one scientist thought it would be funny to put a penis head on top of the rocket. Realising how effective its flight was he refined the penis tip into what is now the modern day rocket nose cone.

Enough to lift a small rocket 5-600 feet.

If it's an average sized rocket, you can make a parachute from a plastic grocery bag. Place a dinner plate upside down and cut or trace a line around it. Cut this circle and attach 4 or 6 x 24 inch pieces of thread to it with scotch tape. Now just tie the loose ends in a knot and attach it to the elastic that goes from rocket body to nose cap. Now your rocket will float down after it's journey into the sky.

I have built one 4 inches long, it worked well with a 1/2A motor.
