Launch pressure is the pressure level of the compressed air inside the rocket and it is directly related to the thrust which is one of the major forces acting on the water rocket. The higher the launch pressure is at launch, the higher the thrust and therefore, the higher the rocket will reach; this also works in the other way. However, having very high pressure is not necessarily a good thing, it can be potentially dangerous. National physics laboratory from the UK recommends the maximum launch pressure to be no higher than 5 bars, which is approximately 5 atm. Having too much pressure can lead to the rocket exploding or other disastrous consequences, this will be further discussed about in the safety
Hot Air Balloon Analysis In the duration of this project there were many factors that needed to be kept into consideration. The most important was the laws of gas, because the hot air balloon needed to be be constructed enough to withstand the air and have enough room for the hot air particles to move making the balloon have a successful flight. Due to the hot air particles move as a faster rate making then collide to each other which causes the balloon to have enough energy to take flight. While actually launching the ballon I began to see the balloon that did take flight and those who did not. In the beginning of the class launch many of the hot air balloon were successful.
The transferring between kinetic and potential energy happens throughout the ride, but, there is some energy that is not transferred back and forth between the two energies. And this would be because of friction (Energy). Friction is the force that acts against moving objects and causes them to slow down, or in this case, lose some of its kinetic energy. Friction also causes the ride to have thermal energy that has no effect on the roller coaster besides heating up some of the track (Physics). That fact is why many roller coasters have their tallest hill at the beginning, also, at the top of these hills, it is possible for riders of the coaster to experience weightlessness and feeling heavier at the bottoms of the coaster (Physics).
The balloon is filled with air through pumping or blowing. It must not be over filled because you need to leave room for the gas inside to expand. It is best to use a party balloon instead of a water balloon. It decreases the chance that the balloon will pop. 3.
Analysis: Although only a simple water bottle rocket, it still applies to basic rocket theory. The simplest equation which applies is Tsiolkovsky's equation which describes a device that can apply acceleration to itself (a thrust) by expelling part of its mass with high speed and thereby move due to the conservation of momentum. In short the momentum which the rocket gains is that momentum which the water loses as it is expelled. The equation is: ∆v=V_e ln(m_o/m_f ) Where: ∆v = change in velocity (m/s) V_e= velocity of exhaust leaving nozzle (m/s) m_o= initial mass of rocket, including water mass (kg) m_f = final mass of rocket, after water is expelled (kg) Velocity of exhaust can be calculated by: V_e=√(2(p_in-p_out ) )/ρ_w Where: p_in= internal
The strengths depending on what surface you use to rub against the balloon if its either nylon, fleece, or rayon. Static electricity is a neat phenomenon, because it could evolve into a way to harness this energy, it could lead to much more energy to power a Static
Moreover, if there were no air resistance, then the skydivers would continue accelerating until they hit the ground. For objects falling through the air, the formula is represented as: psgV – pagV – FD = psVa Where: ps =The density of the falling object pa = The density of the air it’s falling in FD = The drag force g = The gravitational force V = The volume of the falling object. a = The acceleration of the falling
The raised temperature also allows the star to begin to fuse heavier elements to supply the energy it needs. Helium can be fused into carbon, carbon can fused into oxygen and silicon into iron. However, iron does not release energy once it has been fused and this leads to the core collapsing, because the iron core cannot support itself with gravity pulling it inward. Once the collapse happens, which happens in less than a second, a cataclysmic explosion is
There are two problems with this. One is the more weight the fly wheel has, the more dangerous it is because it is a larger amount of potential energy that could be released in an uncontrolled environment. It has a 1:1 increase of power (mass) as the weight of the fly wheel increases, the power output increases by that same amount. Our fly wheel is made out of carbon fiber which is considerably lighter than their steel ones. When that fails, the flywheel turns to dust thus there is no potential danger from steel fragments.
A simple exercise that creates lung capacity is blowing up a certain amount of balloons each day. Blowing balloons works out the intercostal muscles responsible for spreading and elevating your diaphragm and ribcage. This allows lungs to absorb oxygen, alter its chemical composition while still in the lungs, and expel carbon dioxide as exhaling is commenced. Balloon blowing, while effectively exercising the lungs' ability to expand and take in air, does not affect the size or number of alveoli contained in the lungs. Alveoli are air sacs that disperse carbon dioxide during exhalation and oxygen into the blood during
Genius When using gas in the egg drop challenge, it spreads the amount of energy transferred from the ground to the egg. Making the energy from the ground to the egg less, because if you look closely at a balloon filled with air. When it hits the ground, the gas in the balloon spreads out inside the balloon, and then contracts back. The solid object (the egg) on top of the balloon will sink into the balloon, because it’s a solid and heavier than the gas in the balloon. Let’s say you have an egg that weighs about one pound, you have to build a sculpture that slows down something moving at 9.8 meters per second.
The science behind the different sound effects is not as simple as it seems! Just about the Gunpowder? It’s easy to assume that the explosion of the gunpowder is behind the sound and that’s it. But it isn’t quite as simple as that since different sound affect require a bit more chemistry. Furthermore, the explosion of the firework isn’t the only occasion for the sound.
The Law of Inertia is the net force of the object greater than the gravity pulling it down and it will stay at rest until something happens(Getting a Bang Out of Breath Spray). It stays at rest until an unbalanced force makes the object go into motion( Getting a Bang Out of Breath Spray.) Is it true that when the kinetic energy of a canister launched straight up is at its maximum, the potential energy is near zero, and vice versa. It is false, the potential energy reaches its maximum during flight but returns to 0 when the canister reaches the ground(Getting a Bang Out of Breath Spray). What would a graph of pressure in the canister vs. time after spark ignition look like?
The slight increase changes in mass were due to the increase of pennies. The property of density which is independent of the amount or size of the material used to find out what actually caused the change in mass. The slope of linear fits for the mass and volume graph gives us the average density for the pennies. The hypothesis was accepted because the data supports that the more pennies added increased the volume. The laboratory experiment worked very well.
Have you ever wondered if a balloon can self inflate? How big will the balloon get when different acids are used? If the vinegar reacts to the baking soda more, will the balloon blow up more? The hypothesis is that the balloon with the vinegar and baking soda will inflate more. It needs to be explored because different acids react differently with the baking soda.
