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.

Physics is the study of everything that matter and energy effect. Since all objects that take up space have energy, every object in the world is studied by physics. Physics deals a lot with forces, such as normal force, gravitational force, and frictional force. A simple example of these forces is a pen being dropped. The force acting on the pen is the gravitational force. There is no other object under the pen to keep it from falling, so the pen will keep falling until it hits the floor.

A researcher can state that a measure is valid when it measures what it’s designed to measure accurately.

Scientists use significant figures to show exactly how much information an measurement contains. To give fewer digits that one knows would be withholding information about the accuracy of a measurement, and to give too many would be exaggerating the reliability of the measurement. When measuring, it is important to report all digits that one is certain of, along with one more estimated digit. The final digit of any measurement is estimated. The unreliability of a measurement, therefore, is plus or minus one unit of the rightmost number. Accordingly, the most precise measurements have more significant figures, and the least precise measurements have fewer significant figures.

¨A test is completely reliable if you would get the exact same results the second time you administered it. All tests have `measurement error´. This means an individual's score may vary significantly due to testing conditions or the test-taker's mental or emotional state.¨ (¨What´s Wrong)

▪ We shouldn’t forget to include the experimental error in the results exposed in the recollection of data.

In this lab a car was created of our own making. The purpose of this lab was to use the tools given to us to create a self propelled car with speed attempting to reach the greatest distance possible. Physics is relatable to this lab because the success for this car requires the use of engineered force resulting in the distance and speed components coming to play. The amount of materials used to make the car has a definite influence in the car’s mass, likewise effecting the acceleration. How smoothly the wheels coincide with the floor will depict the amount of friction being created which as well connects back to acceleration. Physics endeavors those key elements therefore creating a relationship with this lab. Having said this, the basis of this lab reflects the very fundamentals physics is based on.

It is no question that Galileo was an influential scientist in his time and still is today (picture located on page 6 from google.com). Though his most notable discoveries were in the field of astronomy, we cannot label him simply as an astronomer. He authored many important works including, Sidereal Messenger (also known as Starry Messenger), but unfortunately, due to the power of the Catholic church in his native Italy, his work in astronomy was widely rejected by his countrymen. His contributions to physics also place him in the ranks of the greatest scientists of all time. Without Galileo’s contributions to astronomy, mathematics, and physics, we would lack many basic understandings of the universe and

Using these diagrams, it is easier to calculate an approximate value for both the parallel component of the normal force and the maximum force of the eddy currents. The mass of the cart m remains constant at 507.85g ± .01g, and the peak acceleration due to eddy currents in the 90 cm run was -.7 ms-2 ± .1 ms-2. These values can be inputted into Newton’s Second Law:

If you picture a group of high school seniors blankly staring at a smartboard, fighting off sleep, despite the fact it was the last class of the day, that was my physics classroom. I was one of a small group that sat near the front of the classroom and made an earnest effort to learn something each day. The class had a set routine: lecture, set of worksheets, one day of review for the test, and then the unit test. Our teacher was always extremely helpful during the work time given for the paper assignments, and would bring around props that related to the unit, but students would not take advantage of the time, because there was much leniency with due dates and even the test date. I can learn in circumstances like that physics classroom quite successfully, because I liked the aspect of independent work with the option to consult with peers or the teacher. The group I sat with was always animated and discussing the topics presented in the worksheets, collaborating and effectively using our resources. A majority of the rest of the class was always bored, and when they did engage with each other, it was not on topics related to physics. Compared with what was described in Appendix 1, the group I sat with was active and involved, but we were the clear minority. Unlike the best schools that the author mentions, boredom was the norm in my physics classroom. My group was never challenged by the work we were completing, as we sped through the worksheets after minor discussion, what

In the 21st, in our science classes, we are taught to believe that our world is actually made up of particles as the smallest constituents of matter. We are told that particles behave like waves because it makes no sense to teach that a particle moves faster than the speed of light, that particles can cause interference with one another, among other ridiculous things that we just never imagine a particle to do. What we are not told is that we never had to think about the smallest elements of matter, also known as, quanta, as particles. Instead, we can describe quanta as being excitations of fields, i.e., waves. There is no supporting evidence that a wave can behave like a particle, the evidence only points to experiments evaluating the data using wrong techniques, and assuming that a particle was in the place of a wave.

n the early 20th century it was discovered that particle such as the electron could be in two locations simultaneously . The behaviour of these particles is governed by quantum mechanics, a set of outlandish physical laws. Laws that allow these particles to be in an infinite number of states at a time, allowing them to be be in an infinite number of locations with an infinite range of characteristics simultaneously. However, can this observed behaviour be applied to actual people? It seems strange to think that I am in many places at one time but I will be exploring the implications of this if this is the case.

Being one of the greatest minds of 17th century, Sir Isaac Newton still continues to influence the field of mathematics and physics. He has made revolutionary discoveries in the domains of motion, mathematics and optics. On top of that, he is also remembered as the founder of modern physics ' principles.
