Essay about Physics Behind Flying Airplanes

Floating cars have always been a cool idea to people, especially with movies like back to the future.

Newton’s second law of motion states that “The change in velocity in which an object moves directly proportional to the magnitude of the force applied to the object.” This can be explained by the equation F=MA. The acceleration of the ball, (A), is determined by the force applied, (F), divided by the mass of the object that is being moved, (M).

is the air resistance on any given object that is moving in the presence of air. In the

If you hit an object with force than it will accelerate, but if the object has too much mass then the force cannot carry the object. The smaller the mass, the less force is needed to propel the object. The more the mass, the more force is needed to propel the object. For our rocket, the force came from the force of the compressor. The force carries the rocket and travels at an accelerated velocity. We put 500mls of water in the bottle. If we put too much water in the bottle, the mass would be too much for the force, from the air pressure, to carry. If we put too little water in the bottle, then the force would not be enough to propel the bottle to its maximum height. It was pretty hard to guess the right amount of water to put in the

12. Forces of 3 N and 4 N act at right angles on a block of mass 5 kg.show that the resulting acceleration is 1 m/?

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

Ever since the development of the first few examples of rocket power, it was evident that this was technology that was going to change the face of the world forever. Since missiles and other weaponry were now able to be launched across continents and even oceans, it made the world feel a whole lot smaller. In turn, this was the technology that “had its ultimate foundation in the simple power rocket which originated as a weapon of war” . However, this technology underwent an extreme transformation over time and was eventually the basis of the technology used to put spacecrafts up in space. One of the main rockets that is going to be discussed in this paper is the V2 rocket designed by the Germans during World War II, as much of the technology that put spacecrafts in space came from this rocket. Another aspect that is going to be

Force is equal to the mass of an inert object multiplied by the acceleration of that body

The purpose of this experiment was to investigate the effects of different masses hoisted by an electric motor from ground level to a height of 1.29 m. The main purpose was to look how a change in mass affected the efficiency of our motor, but it did affect other variables such as power, current, force, etc. For this experiment, our hypnosis is that as mass increases, the efficiency increases. Because in the equation for efficiency, efficiency=gain in potential differenceelectrical energy used, gain in potential difference = mgh, the mass of an object has a direct relationship with the efficiency of the motor. In this equation, we see that efficiency is affected by the mass that is lifted, gravity, the height the mass is being lifted, and the amount of energy that is put into the system. We can see that mass, gravity, and height has a direct relationship while inputted power has an inverse relationship with efficiency.

5. What’s really meant is that the forces are the same but going in different directions as a mirror image of one another. So when one force is going for example 2 newtons in a positive direction, the same amount is going in the opposite direction.

The shorter the intervals the greater the force. The 20ms interval causes the greatest force.

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

1. Why does the force begin to decrease with time? Note that a decrease in force indicates muscle fatigue.

Let’s say a plane is flying at a constant velocity and is not changing in altitude. Newton’s first law states: “Any object at rest will remain at rest or an object in motion will remain in motion unless a force acts on it.” Newton’s second law tells us that the sum of the forces (F) acting on a body is the mass (m) times the acceleration (a) of the body. In the case of our airplane, there is no acceleration because the velocity does not change up or down, forwards or backwards, so the sum of the forces must be zero. (F = ma = 0) In the case of the up and down forces, we know that the weight of the plane is acting down, so the counteracting lift force must be of magnitude equal and opposite the weight (which can be very large depending on the size of the airplane in question)!

The Flight Path of Airplanes Over Neighborhoods The houses can’t be unbuilt, and the airports can’t be torn down.  But maybe the fences can be mended.  –Robbie Sherwood   In the past 10 years, many cities across the country have outgrown the planner’s expectations.  Unfortunately the airports that were built 20 or more years ago, have not grown with the cities.  Phoenix has tripled in size in the past 10 years.  The tripling of air traffic has not had anywhere to go.  The same two runways that have been serving the city since 1935 when the airport was built have been extremely over loaded.  It is not just happening in Phoenix, a few years ago Denver received a new airport to relieve the overflow of traffic from the older Stapelton
