Physics Of A Physics Experiment

Experiments are a scientific procedure which is used to test a hypothesis. There are two different types of experiments which are available to the researcher, these are laboratory and field.

Experimental design is a process by which a researcher takes a hypothesis, designs an experiment to test for the hypothesis, collects the data from the experiment, analyzes it and draws conclusions about the results. It is used to determine cause and effect and is used in all forms of science from physics and biology to psychology and sociology.

The scientific method is used during experiments to find a conclusion and or reason as to why an event or something happens.

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.

If a hypothesis is verified using experimentation then what might be the next step in the scientific method?

A hypothesis is tested through an experiment. To have effective testing, the experiment must have controlled variables, one control (without independent variable), and an experimental group.

Experiment- A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (dependent variable). By random assignment of participants, the experimenter aims to control other relevant factors.

The next step is to form a testable hypothesis, or educated guess. A hypothesis must phrased in a way that in which another person can test the same hypothesis to verify or discredit it. After the hypothesis is formed, the experimenter must choose and appropriate research study. For example, if a scientist want to do a study about the behaviors of a particular person, like in the case Phineas Gage and the psychological affects of the iron rod that shot through his head, than the scientist may want to conduct a case study. Once the research method is established and the study has been planned out, then it is time to conduct the experiment and collect the data. The final step is to analyze the data to see if it supports or rejects the hypothesis. If the results do not support the hypothesis, then one should revise their hypothesis. If the results do support the hypothesis, then the study should be replicated to validate this study. Sharing the results of the experiment with other members of the scientific community is also an important part is advancing one’s understanding of the particular

Experimental design research tends to use math and statistics to try to prove or disprove a hypothesis. Within an experimental design most of the research is controlled and leaves little room for error. One advantage of experimental design is that it is hard to disprove the results. However, a disadvantage is that because the conditions are controlled that makes the results too perfect. If the same experiment was conducted in an uncontrolled setting, such as the real world, the results would vary.

The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments, in order to try to construct a reliable, consistent, and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First, the scientist must observe the phenomenon of interest. Next, the scientist must propose a hypothesis, or idea in which the experiments will be based around. Then, through repeated experimentation, the hypothesis can either be proven false or become a theory. If the hypothesis is proven to be false, the scientist must reformulate his or her ideas and come up with another hypothesis, and the experimentation begins again. This

The term scientific method refers to a way of investigation or the acquisition of knowledge through the testing of a theory or hypothesis, then working through measurements (observation and empirical notes) to come up with a result, which should prove or disprove the original theory. Thus, the basic method consists of a) formulating a question or hypothesis, b) designing an experiment or means of collecting data, c) observation or experimentation, d) analyzing

science a hypothesis is always trying to be proven like Galileo was doing but it

Science is the knowledge gained by a systematic study, knowledge which then becomes facts or principles. In the systematic study; the first step is observation, the second step hypothesis, the third step experimentation to test the hypothesis, and lastly the conclusion whether or not the hypothesis holds true. These steps have been ingrained into every student of science, as the basic pathway to scientific discovery. This pathway holds not decision as to good or evil intention of the experiment. Though, there are always repercussions of scientific experiments. They range from the most simplistic realizations of the difference between acid and water to the principle that Earth is not the center of
