What is the purpose of bottle rockets?
Background Information: Bottle rockets are excellent devices for investigating “Newton’s Three Laws of Motion”: 1st Law – A rocket will remain on the launch pad until an unbalanced force is exerted, propelling the rocket upward. 2nd Law – The amount of force depends upon how much air is pumped inside the rocket.
What does the bottle rocket have to do with Newton’s third law of motion?
Bottle rockets are excellent devices for investigating “Newton’s Three Laws of Motion”: 3rd Law – Finally, the action force of the air (and water) as it rushes out of the nozzle creates an equal and opposite reaction force propelling the rocket upward.
What do you need for a water bottle rocket?
What you need to make a bottle rocket
- an empty plastic bottle.
- cardboard made into a cone and 4 fins.
- a cork.
- a pump with a needle adaptor.
- water.
Are water bottle rockets illegal?
Sale and regulation. Bottle rockets are specifically illegal in many jurisdictions, even those where most other consumer fireworks are legal. They are sometimes considered to present a unique hazard, due to their ability to fly in many directions other than vertically.
How does weight affect a bottle rocket?
When properly weighted, the rocket’s nose section will actually pull the rest of the rocket behind it. However, too much weight will slow its performance, just as too little weight will cause the rocket to spin around its center of gravity.
Why are flying fireworks illegal?
Fireworks that are prohibited under federal law may have large quantities of pyrotechnic material, dangerously short fuses or toxic chemical content. Some of these illegal fireworks, like cherry bombs or M-80s, can be explosive enough to amputate limbs.
How to make a rocket out of a bottle?
build a rocket out of a plastic bottle, using water and air pressure to generate the thrust. design a nose cone and fins that help the rocket travel as far as possible by increasing stability and minimising drag. investigate some of the variables that may affect the distance travelled or height reached by the rocket.
Why is water used as a propellant in rockets?
Before launch, the bottle is filled with some amount of water, which acts as the “propellant” for the launch. Since water is about 100 times heavier than air, the expelled water produces more thrust than compressed air alone.
How are Bottle Rockets evaluated for their quality?
Evaluate each bottle rocket on its quality of construction. Observe how well the fins align and attach to the bottle. Also observe the alignment of the nose cone at the top of the rocket. Evaluate the design and quality of construction of each bottle rocket by measuring and comparing the altitudes that the rockets reached.
