Why do boomerangs come back? When I was young, I thought boomerangs were magical. I wasn’t sure if they actually worked in real life, so I decided to make my own to test the idea. I took a pizza box, cut out a boomerang shape from it, and threw it. It didn’t come back. I tried again and again, but I couldn’t make it work. I was bewildered as to why my boomerang didn’t come back! As it turns out, I had constructed it incorrectly. I thought a boomerang was just a flat, v-shaped piece of material

DISCUSSION The primary aim of this study was to observe the force characteristics occurring during the SL under different attentional focus conditions. Data was collected in a controlled laboratory setting where conditions were counter-balanced with participants. It was hypothesized that lifters would have a larger propulsive impulse and max rate of force production in an external AF environment. The null hypotheses were accepted due to no significant differences in force characteristics during

Introduction: The purpose of this experiment was to measure the magnitude of velocity in a flat plate boundary layer in which the pressure was constant. A pitot tube located at the top of the test section that was used to determine the total pressure across the boundary layer. The Pitot tube needed to be able to more along both horizontal and vertical directions for accurate measurements. Five different tubes, aligned along the x-axis, were placed under the wind tunnel test section to measure the

The Physics of a Golf Ball The first written reference of golf was in 1457. Golf balls have had extraordinary changes since that time; they've gone from leather pouches to dried gum to today's dimpled balls. These dimples help decrease the drag and increase the lift. Different forces are applied to the golf ball when struck by the club. Golf clubs have grooves to create backspin. And then there are different variables that affect how a golf ball will travel, these include: lie angle and

Controlled Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation, could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of

real airplane. There are four crucial things In order for a plane can fly, These are the aerodynamic forces. The four aerodynamics are, Lift, thrust, gravity, and drag. The lift is the force pushing the airplane to make it go up. The thrust is when you are throwing the airplane. Gravity is the force that pulls the plane down. finally, drag is the thrust pushing against the begining thrust slowing the plane down. my hypothesis is, If the tail has two pieces bent down then the plane with fly farther

Charlie starts dismissing his employees, he learns that other factories have found niche markets to cater to. Charlie finds a niche market in shoes for drag queens, these Men find the heel often breaks due to them often being heavier than the shoe was designed for. Charlie’s inspiration for the “kinky boots” is Lola the shimmering, flamboyant drag queen. “Kinky Boots” follows Charlie and Lola through the fabrication, production and marketing of the shoe.

Investigating a Factor that Affects the Rate of Decent of a Parachute Aim- To investigate one factor that affects the rate of decent of a parachute. Plan There are many factors that affect the rate of decent of a parachute, some of these are: The weight of the object on the end of a parachute, the weight of the parachute, the length of the strings on the end of the parachute, the surface area of the parachute, and the shape of the parachute. As we were only

It’s a bird! It’s a plane! It’s Superman! In 1938, Action Comics #1, released the first Superman comic to the public. Superman, also known as Kal El, has shown many different powers since his first debut in 1938. This paper will discuss various topics about four of his major powers and explain why they are all impossible for anyone to achieve in real life. Superman’s four major powers that will be discussed in this paper are X-ray vision, being able to fly, super strength, and invulnerability.

Dolphins are a widely known mammal throughout the world. Mainly known for performing at aquariums such as sea world, not many people have seen wild dolphins. Being from the Florida Keys I have been lucky enough to be able to see these animals in their natural habitat. Dolphins are part of the family of toothed whales that also include Orcas. They normally grow to about 8 feet long and weight up to about 600 pounds. They are carnivores and their diet consist of different species of fish and squid
