The Helicopter With A Helicopter Essay

In the ‘Breaking Through Uncertainty—Welcoming Adversity’ , Jim McCormick talks about the latest one of his thousands of parachuting experience. In a fine Saturday, he goes for the 2123rd parachuting. Not like any of other time, his 2123rd time parachuting puts him in a life-threatening situation. This time he couldn't fix the twists in the lines which normally the parachute opened with its initial opening. The author becomes really panic and feels

Based on a previous paper airplane experiment coducted on balancing lift and weight, you can change the center of gravity by placing weight on different parts of the plane. The further towards the nose of the plane the more likely it'll nose dive. Moving the weight towards the tail will cause the nose to go up. (Science Buddies, 2013). Given this infomtion, I hypothesize that placing weight on the center of the paper airplane will give it the center of gravity it needs to fly the furthest distance.

33. Why is it that a cat that falls from the top of a 50-story building will hit a safety net below no faster than if it fell from the twentieth story?

The video begins with Peter Donnelly, a statistician bringing up a coin toss thought experiment. The audience was to guess how often the pattern of coin flip would land Head-Tail-Tail compared to the other pattern of Head-Tail-Head. The three options were: "A" the number of coin tosses for the pattern HTH will be greater compared to HTT. "B" both patters would take on average the same time to repeat themselves. "C" the number of coin tosses for the pattern HTT will be greater compared to HTT. I chose option "B" as my answer because every coin flip is a 50/50 chance of getting either head or tail so on average both patters should repeat them equally. I was surprised to find that most people also vote option "B", but in fact the odds favor option "A". On average, it will take relatively less tosses to get the pattern HTT than HTH, about 8:10 tosses. This is because the pattern HTT has a larger chance for success because a third of the pattern is always established while the pattern head tail head appears in clumps.

One split open as it landed on the deck. The first of the two would detonate in 94 seconds.

The purpose of the experiment was to see whether or not adding mass to a paper airplane would affect its hang time.

My partner and I been testing how far paper airplanes will go and how long will it last in the air.We been testing many airplanes out,the are planes are called a dart,an eagle,and a glider.The dart doesn’t go that far and it doesn’t even stay in the air for that long.The eagle goes very far the best score we got is 108.5 that was with attachments.The final are plane we was the glider,the glider stayed in the air for 4.33 seconds.So our best one was the eagle.

The reaction time was calculated by using the formula t=2d 982. The variable ‘d’ is the distance the ruler fell, and ‘t’ is the reaction time.

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

properties that give it an equal chance of landing on heads or tails. Now, the problem has been

The spinning would take the longest to fall to the ground; however, it was difficult to keep the results consistent. Our expectations proved to be correct by the results. The parachute device had an average fall time of 2.26 seconds while the spiral device had an average of 2.08 seconds. Though we did not have the longest airtime in the lab, our devices performed well without difficulties.

If the object was thrown upwards with an speed of 6 m/s. How long will it be in air, if you catch it when it returns?

Theirs landed 3.55 seconds, and had a very soft landing with very little impact. One of their strengths was definitely the amount of balloons they had attached to their contraption to increase drag.We had some very important strengths and weaknesses that we discovered in doing this experiment. One of our weaknesses was the lack of balloons we had to increase drag, thus reducing the impact to a lower level. We had two main strengths. the first strength was the cotton surrounding the popsicle stick protecting platforms. The cotton prevented less impact even though there wasn't any drag to slow the fall. The other strength we discovered was the amount of rubber bands we had used on the contraption to keep things tight, steady, and in place. The rubber bands help out a lot, especially when you're dealing with trying to stabilize popsicle stick platforms and securing the egg. if I had the chance to fix or add any supplies, or build anything on the contraption differently, I would definitely increase the amount of balloons to help with cushioning and slowing down the fall, and build a different kind of platform that would be more sturdy and easy to work

The original design of the rotocopter was straightforward. Flap A and Flap B were to be folded in towards each other, along the dashed line. Rotor A and Rotor B were to be folded in opposite directions. The hypothesis of the experiment was as follows: If the rotocopter is put onto construction paper, it will have more air time. To be ensured that only one variable was tested at a time, the rotocopter was dropped from the same height every time. Not only this, but the rotocopter was checked to make sure nothing was changed each test.
