Physics is Everywhere Physics is like math; it is always being used everywhere, whether we are conscious of it or not. With the use and knowledge of physics, one can take into account that knowledge to help them perform a deed more successfully and efficient. Although skydiving and weight lifting aren’t the only activities that involve physics, I feel that they are some of the most interesting and benefit seeking activities. Without the knowledge of physics, skydiving wouldn’t be as safe as it is today and weight lifters wouldn’t be able to lift five times their weight. The history of the physics of skydiving and weight lifting has been affected by implications socially and economically. Over the years, these activities have been altered due to increasing knowledge of physics, and this knowledge will continue to expand as time elapses. In 1797 the Frenchman Andre Jacques Garnerin performed the first parachute plunge from an aircraft using a basket below an open parachute, which was made of silk and solidified with supporting poles (The History of Sport Parachuting). When the first parachute was dropped, physicists didn’t have a wealth of knowledge about the physics that supported skydiving. Ever since the first drop, skydiving has been an evolving sport, as this is due to the developing knowledge of physics. Skydiving is perceived as a very risky sport in the eyes of the public; therefore, in order for the sport to continue, physicists needed to discover ways to reduce the risks involved. They were successful in doing this by developing better equipment and techniques. The economical impact of skydiving has been huge. The research involved in the design of the chute, the materials used, and the engineering invo... ... middle of paper ... ...s. “Physics in Action” 4 June. 1997. 15 Nov. 2005. http://www.glenbrook.k12.il.us/gbssci/phys/projects/frig/piabycbu/pia1.html - George, Jeff. “Physics and Skydiving”.

The size of the parachute was a little small, so next time I think I should make the parachute larger. It would as said before, slow down the rocket more
For my egg drop project I used 4 cardboard cut outs, half of a bottle, yarn, popsicle sticks, 2 balloons, and a garbage bag. I used the popsicle sticks & the cardboard cut outs to build a box to surround the egg. Then, I glued some yarn to the bottom of the box for cushion. After the glue was dried, I put the egg on top of the yarn and glued the half of bottle around it. I attached the 2 balloons on the opposite side of the box. After doing all of that there was only one thing left to do, which was make the parachute. When I made the parachute, I cut a garbage bag in half and folded it into a square. Then, I cut four pieces of yarn (same length) and tied it to the box from each side of the parachute.
The historical results of this experiment by determination of the charge to mass ratio of an electron allowed physicist to work out the miniscule mass of an electron through the use of an external magnetic field. Magnetic fields apply a magnetic force on charged particles perpendicular to their direction of motion and to the magnetic field itself. This allows for the magnetic force to act as a centripetal force which then, through analysis, allows for the determination of certain charged particles through the analysis of their curve radius. In lab 15, Measurement of Charge to Mass Ratio for Electrons, the objective was to measure the charge to mass ratio (e/m) of an electron through the use of a mercury vapor chamber. This was done through the graphical analysis by the linearized equation (4). The goal was to construct a linear graph in which the slope and slope error was calculated using the Linest function, the slope than allows for the derivation of the charge to mass ratio of an electron. Error propagation (error formulas) was also used in this experiment to account for sources of error that could have occurred.
Sir Isaac Newton’s laws of motion affect every aspect of life, and there are examples of those forces at work all over, not just in baseball. The laws of physics are at play in even the simplest of movements or actions, facts so widely accepted that you don’t even have to think about them. Athletes don’t think about the physics behind their movements before they throw a ball. However, all the information above demonstrates just how much a sport like baseball depends on the laws of physics. Without these forces, America’s pastime wouldn’t be very entertaining to watch or play at all.
With the knowledge of these concepts of physics, one should now be able (with training) to safely partake in skydiving. A safe landing should not be an issue!
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
Metaphysics can be defined as an attempt to comprehend the basic characteristics of reality. It is in fact so basic that it is all inclusive, whether something is observable or not. It answers questions of what things must be like in order to exist and how to differentiate from things that seem real but are not. A common thought is that reality is defined as what we can detect from our five senses. This type of philosophy is called empiricism, which is the idea that all knowledge comes from our senses. An empiricist must therefore believe that what we can see, touch, taste, smell, and hear must be real and that if we can not in fact see, touch, taste, smell, or hear something, it is definitely not real. However, this is a problem because there are things that are real that cannot be detected by our senses. Feelings and thoughts can not be detected, so according to a true empiricist, they must not be real. Another example that is listed in the textbook is the laws of gravity (Stewart 84). This is something that is in fact proven and we can see the effects of it, but we can not see gravity itself. Once again, this would not be considered to be “real.” However, there are certain things that some people consider to be real, and others consider them not to be. This typically comes into play when discussing religion. Some people consider God to be real although they can not “sense” Him and others say that He is not real, possibly because of the fact that they can no...

In conclusion, physics is involved in all things around us. Whether in a classroom, in a car, or playing basketball physics concepts can be applied to the action. Although it is not very practical for a person to stop and calculate the angle, velocity, and position, the use of physics does make it understandable and possible. As much as the physics of basketball seems insignificant and ludicrous, to calculate the principles are in fact very valuable to a player without them even knowing they are doing physics.
For centuries, human beings have unknowingly used the very physics principles seen in the roller coasters of today in pursuit of not only thrills, but also survival. As early as 30000 years ago, our ancestors were using some of the most basic laws of physics seen in roller coasters today to their advantage. Although they didn’t quite understand why, when they threw a wooden spear high into the air at a woolly mammoth the spear would fall to the ground accelerating at every second. Of course, they were demonstrating gravitation. Physicists of the 16th century knew how to harness the law of gravity as well, using it to construct the first roller coaster- consisting of simple ice slides accelerating down 70-feet slopes before crashing into giant piles of sand (the latter part demonstrating another important physics principle: inertia.) As the centuries prog...
Physics can be found in all aspects of our lives and the world around us including the activities in which we find the most enjoyment. They may not be noticeable to the naked eye or even to our senses but they are there and when we become familiar with the concepts of physics then we began to ‘see’ physics everywhere.
Skydiving has been around since ancient Chinese times as a form of aerial stunts. Leonardo da Vinci and the Chinese are both credited for creating the parachute, but it was really in the 18th century when France both created it and used it by basically throwing themselves out of planes. Little did anyone know that skydiving would be one of the craziest sports today. Jumping out of a plane two and a half miles up into the sky would not be someone’s idea of a normal day. As bad as two and a half miles up in the sky is, try doing it traveling at a rate of one-hundred and sixty miles per hour with just a parachute to save you. To many people this would be a nightmare; but to some of us, it is the biggest thrill of our lives.
In this assessment of the projectile motion of an object, I found that it can be applied to many useful situations in our daily lives. There are many different equations and theorems to apply to an object in motion to either find the path of motion, the displacement, velocity, acceleration, and time of the object in the air.
During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.
In real life situations, there are many applications of physics. Physics is applied in almost everything we do and everything around us from household chores, in school and in
