The Physics Of Physics : Physics

The objectives of the project were to design and build a car from a mousetrap and other materials, the main goal being to reach maximum displacement, and to use the design to demonstrate a personal understanding of the principles of physics incorporated. While our car did move and function, it did not reach a distance of ten meters, a set goal. Overall the goals, while not met completely, were at least somewhat accomplished.

To create a mousetrap car and measure its performance. We will also see where force and energy is impacting on the performance, for example friction will impact on the cars performance as it generates heat and slows to car down thus meaning that the car may not travel as far as it should. Another force that is demonstrated in testing of the car kinetic energy, without kinetic energy the car would not travel at all.

For years I have shown a passion for physics and I aspire to read it at a deeper level because of its many phenomena and applications, and the need for skilled physicists in the world, as without them, civilisation would struggle to thrive. The thought process and unique perceptions that physicists have are key in driving businesses and other innovations. Furthermore, society is hugely reliant on technology, resulting in physicists becoming increasingly important to both maintaining and creating new technological ideas. For example my work experience at Sky allowed me to see how the approach that the physicists there took enabled them to be very successful in their line of work. More importantly however, the beauty of physics is found on an intrinsic level which allows us to understand the universe we live in. For thousands of years, religious beliefs dominated explanations for important ideas such as how the universe was created, the afterlife, and of course the question of a deity. Religion shaped society for many years, but the intervention of physics has bravely challenged these once readily accepted views, creating a society that consists of

1. Find the westward component of a resultant vector 85.42 unit, 23º W of N.

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form, Efficieny- e.motor=85%, combustion= 20%

What this means is that an object will continue in its current direction and with the same net force indefinitely, or until an outside force is applied to the object. In the case of the pull-back cars, this means that, without the force of friction, the cars would continue on in the same direction forever, but because of friction, the cars have to stop their motion eventually, and that distance can be used as a measurement of the friction inflicted upon the car. Furthermore, Newton’s second law of motion “the relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.” All this means is that, the higher an object’s mass and acceleration, the larger the object’s net force is. This relates to the physics of the experiment because, for the force of friction to completely stop the car, its force must be equal to the toy car’s acceleration times it’s weight. There are several variables that could have affected the experiment’s outcome. For one, the toy cars were fairly unreliable and one toy car could have provided different amounts of power during the different tests, which would have negatively affected the results

Writing is taken for granted nowadays. Thus, people don't take in consideration how lucky they are to be able to read and write. I can still vividly remember how when I was very young I used to get extremely angry for not being able to read the newspaper that my grandfather used to carry around. For that reason, there is a lot of importance to reading and writing, and I'm glad that throughout this year I was able to grow as a writer.

In this lab, we were applying Newton’s laws of force on a moving object. In this

Like the toy doll, some would say that a user begins to have an imagination while playing with the toy truck. However, the user experiences no difficulties or tasks when playing with the toy. Despite all of this, a young user could learn the rudimentary characteristics of friction and scientific laws when playing with this toy. For example, every time you push the truck it will eventually come to a stop. This process exemplifies the scientific law of friction. Overall, the toy truck could be an in-between toy teaching more intelligent ideas of science but for those who do not understand, the toy does not actively engage

1. Heat passes through the atmosphere by way of radiation, conduction, and convection. Radiation is heat provided directly by the sun Radiant energy is another word for radiation. Energy from the sun travels on a direct path through space to earth in the form of electromagnetic waves. For example, that heat you feel from the sun while outside when it is blazing down on you is actually radiation. Conduction is the movement of heat inside of an object on a molecular level. When met by a heated outside influence, the atoms begin to vibrate as they warm. As they vibrate, they bounce off one another and each atom passes heat on to another every time they touch. While this is happening, the entire object becomes heated. For example, think of a teakettle. By itself, the kettle remains quite cool. As someone places the kettle onto a lit burner of a stove, the molecules that make up kettle begin to shake rapidly. As the particles run into one another, the entire kettle becomes

n this report the students learn and understand the concepts of why they are doing this. For example the pasta car lab, they understood and learning how newton's laws works such as the Newton's first law of motion, newton's second law of motion and, newton's third law of motion. Therefore they knew that Newton's first law is talking about inertia, then again some call it the law of inertia, it is when an object in rest stays at rest and also an object in motion stays in motion. For example, if the students have a vehicle on a hill and they let go of the brake it will roll and it will build up momentum until it's is not on the hill anymore and rolls until it runs out of energy until all that energy runs out that was built going down the hill.

Most car safety devices in the modern day use overwhelming amounts of physics background in order for these devices to be as efficient as they are. Included concepts include inertia, momentum, force and acceleration.

We say an object is in free fall when the only force acting on it is the earth’s gravitational force.

The Physicists is a satiric play written by the Swiss author Friedrich Dürrenmatt about three physicists who are living in the private sanatorium " Les Cerisiers " headed by the last living member of an old regional aristocratic family, Miss Dr. h.c. Dr. med. Mathilde Von Zahnd. The first one thinks he is Sir Isaac Newton, but he is in reality Herbert Georg Beutler, the second one thinks he is Albert Einstein and his real name is Ernst Heinrich Ernesti. The third physicist, Johann Wilhelm Möbius is different, he has got no second identity but he is in this sanatorium because King Solomon speaks to him.
