Abstract
Spinning objects such as Frisbees possess unique flying characteristics. They are in essence spinning wings gliding in mid-air propelled by the forces of torque and aerodynamic lift. The relationship between Newton’s Laws of Motion and the flight of the Frisbee will be discussed. This paper will attempt to highlight and show the different physical motions involved behind the spinning edge of the Frisbee and the similar forces it shares with other heavier winged objects. Lastly, how major improvements in the redesign of the Frisbee contributed to its increased stability and precision in its flight in the air.
The Flight of the Frisbee
Objects that fly are designed to push air down. The momentum of the air going down

In addition, the quick spring-release action of the wrist and fingers on the Frisbee is a key contributing factor to setting the Frisbee into a spinning motion. This physically powered and precise twist is transferred to the Frisbee in order to launch the disk spinning at the highest possible angular velocity. Angular velocity is the term used to measure the Frisbee’s rate of spin expressed in revolutions per minute (RPM). Prior to the Frisbee taking flight, “the net force required behind each twist is formulated based on how quickly the disk is able to reach its full speed or angular acceleration, versus how much the Frisbee resists being twisted or in this case the rotational inertia” (Fisher & Phillips, 2003, p. 12). As indicated by Newton’s First Law of Motion, inertia is the tendency of the Frisbee at rest to remain at rest and while it is in motion to remain in motion. As such, the amount of twisting force that is needed to produce the highest possible spin on the Frisbee is described as the torque. The torque on the flying Frisbee is the product of multiplying the angular acceleration by the rotational inertia. As stated by Professor Bloomfield (1999), “Rotation is crucial. Without it, even an upright Frisbee would flutter and tumble like a falling leaf, because the aerodynamic forces aren’t perfectly centered” (p. 132).
There are two major external forces acting against the flying Frisbee. To sustain
Baseball is an interesting game that is extraordinarily enjoyable to play. This task is about comprehension the material science of a couple key parts of this game. One may ask what material science could need to do with baseball? Like most games baseball includes physical movement. Baseball incorporates each of the three planes of movement through tossing, hitting, and handling. The greater part of the traditional laws of mechanics can be connected to comprehend the material science of this amusement.
The film The Black Balloon was filmed in Australia and the UK and was produced by (Tristram MiallToni Collette) The story is about the members of a family, the parents and two teenage boys, as they cope with a unexpected challenge. Complications arise because one of the teen age boys, Charlie, is intellectually disabled. The family has relocated to a new area. Because the father has a new positing in the army. Thomas is turning 16.Thomas finds Charlie an embarrassment in public, so when Thomas is attracted to Jackie, a girl in his swim class, Charlie presents any number of obstacles when she drops by their house, The three of them go for a walk during a family birthday dinner. Can Thomas find a
The Flying Troutmans by Miriam Toews showed many experiences related to situations that occur in an individual’s daily life. The novel shows evidence that proves dysfunctional in a relationship such as husband and wife relations, a child and a mother relations or relations between two sisters who live a different life.
The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .
Charlie is a severely autistic character in the film The Black Balloon. This collage was made to represent the world that he perceives around himself, and those things that he finds important. Whilst making this collage, I focussed less on Charlie’s interests and more on how he would see things in the world and how they affect him. His interests are not widely focussed upon in the film, but there are large references to the affect his condition has on his view of the world.
The objective of this lab was to explore the behavior of centripetal acceleration and identify the relationships between the acceleration and several forces acting on the object.
Lacrosse is played with ten people on the field at a time including the goalie. Cradling is the most important part in lacrosse. It is what holds the ball in the head of the lacrosse. This applies to Newton's first law, inertia. An object at rest will remain at rest until acted upon by a force. In the case of lacrosse, ¨the net cradles the ball, which connects to the stick before a player finally acts upon it. A centripetal force exists on the ball as the player throws it¨ (http://www.livestrong.com/article/487887-the-physics-behind-throwing-a-lacrosse-ball/). What causes the ball to
I don’t exactly remember my elementary years as well as I used to but I remember parts of it like my best friend was my cousin Austin we did just about everything together like we used to skate play games, I even played tee ball believe it or not, me a non-sports kinda kid playing tee ball. That all changed after I took a fly ball to my nose, and quit right then. I remember my skateboard my first one that was an ugly off set white with a black stick figure on it. I remember that my usual skate spot was at the school. I also remember this one time I was maybe 4th grade? Austin and I were at Legion Lake honestly it was more of just a pond but it had this huge hill we had a wagon because we bought 2 12 packs of mountain dew. When we got to the
Once an object is in the air its flight path is governed prior to its release. There
The name of the book is Chasing the falconers. The main characters are Aiden and Meg Falconer, who are siblings, Miguel Reyes and Hairless Joe. The setting of this book starts off in Sunnydale, mainly at night, the barn and jail. But since they are always on the run the setting changes a lot throughout the story.
When a baseball is pitched, hit and flies in the air, one or more of the physical principles formulated over 300 years ago by Sir Isaac Newton act on it. Folklore tells how the mathematician and physicist first realized the law of gravity while observing a falling apple. Had Newton watched a baseball game instead, he might have formulated all three laws of motion by the seventh-inning stretch. Pitching Newton's First Law of Motion states that every object remains at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
It may be a New Year, but that doesn’t mean the winter is anywhere close to over. In fact, Ludlow, Kentucky could be facing some serious cold and snow in the next couple of weeks, and it always pays to be prepared. That’s why Ideal Supplies, your local hardware store, recommends that you stock up on your salt/calcium pellets now before it’s too late. You don’t want to be desperate for ice remover when there’s already ice on the ground.
In figure 1, the force of the gravity is pulling the person and the parachute towards the ground because gravitational force makes the object fall quickly. However, the parachute slows the person down because it causes air resistance as it pushes the parachute back up and creates an opposite gravitational force. The forces “push or a pull” are called action and reaction forces, the subject of newton’s third law. During this investigation, the push force is the air resistance and opposite (pull) force is the gravity.
The goal of this project is to work towards answering the question of whether or not football helmets promote neck injuries. In order to gather data, a U of R team made a machine that rapidly changes speed while translating from side to side to stimulate a rotational acceleration and velocity about the head and neck due to an angular displacement. The purpose of this machine is to simulate an unexpected and sudden change in motion of the head in order to analyse the resulting motion. The data collected was the rotational position of the head, the linear position of the cart, and the linear position of a point on the body. All measurements were made with and without a helmet. In order to answer the main question, there had to be a further understanding of how the mechanics of the head and neck change with the addition of a helmet. To achieve this, MATLAB was used to compute the resulting velocities and accelerations, the reaction forces at the neck, and the moment about the base of the neck. From these calculations, it is possible to make observations about how the addition of a helmet affects the dynamics of the head and neck.
