people would still like to travel even if the invention of an airplane never happened? Imagine having to spend days in a car or on a train just to get to you destination‚ would you still want to travel? I believe the invention of an airplane was brilliant. The airplane is not only one of the greatest inventions in the 20th century‚ but also the most wonderful scientific creation of the human history. The inventors of the first airplane were Orville and Wilbur Wright. On December 17‚ 1903‚ the Wright

is when it’s in an airplane built with your own hands. What’s truly remarkable about homemade aircraft are their great diversity of design. They can take the form of biplanes or ultra lights that aren’t much more than a hang glider with a motor and landing gear. Some are as large as commercially built planes while others look and sound like go-carts with wings. They are remarkable because anyone with some mechanical aptitude and a work ethic can build one. Your basic airplane really isn’t that complicated

This essay is a "how-to" essay that fully explains in detail how to make a paper airplane. It also give history of the paper airplane and instructions on how to put it into flight. PAPER AIRPLANE Since early in history‚ man has been fascinated with the sky and possibilities of flight. Improvements in flight‚ especially in the 20th century‚ have revolutionized the world. People can go around the world in less than a day‚ cross oceans in a matter of hours‚ even go from city to city in a fraction

Today I will be talking about paper airplanes and what type of paper airplane flies the farthest also which one stays aloft the longest. Some of the topics I plan to discuss involve aerodynamics‚ drag‚ shape‚ size‚ forces‚ and gravity. Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction‚ when air rubs against the surface‚ and difference in air pressure. Think of a drag like swimming treading through the water you can’t

Math Exploration: The Physics Behind Equestrian Before this exploration begins‚ it is important to be informed of the definitions of many equestrian terms that will be used in this exploration. Equestrian: Of or relating to horseback riding or horseback riders. (Kirkland‚ Sarah) Walk: The walk has a distinct four beat rhythm. When the horse is walking‚ its movement is easily accounted for by the rider. (Kirkland‚ Sarah) Trot: The trot has a two beat rhythm to it. It

THE PHYSICS BEHIND CAR SAFETY FEATURES Cars contain several different types of safety features. These numerous safety features all have their own significance to the driver‚ as well as to the passengers. The purpose of this report is to show and express how physics is involved in automobile collisions and similarly how it is used to prevent injuries during accidents. Isaac Newton’s three laws of motion are used to describe the purpose of the three main safety features that cars are obliged to consist
