Physics 211 Experiment #4 Newton’s Second Law – Atwood’s Machine Newton’s second law (FNET = ma) can be experimentally tested with an apparatus known as an “Atwood’s Machine” (See Figure 1.) Two weights of unequal mass‚ connected by a thread‚ are draped over a pulley‚ as shown in the figure. When released‚ the larger mass accelerates downward and the smaller one accelerates upward. Figure (1a): The Atwood’s Machine‚ showing the pulley and the two masses after a run. Figure (1b): A close

subjects in experiments. The use of human beings for experiments or research can have lasting negative effects on that individual such as emotional and psychological damage. The Milgram experiment even though it was a hoax had a lasting effects on many of it’s participants in both positive and negative ways and is a example of why humans should not be used as test subjects. The Milgram experiment was conducted by Stanley Milgram a assistant professor of psychology at Yale. The experiment wanted to

In 1971‚ The Stanford Prision Experiment was performed in order to see behind two contrasting behaviors that humans can show in a power driven institution. The point was to understand aggressive behavior typically shown by guards or people in the position of power using it to hold reign over the prisoners who in turn respond with submissiveness‚ and see how this relates in real world situations. Achievement of conclusion was the information gathered by the role play of students in an exercise of

step to replicate this experiment is to place the three plant group in each of the containers‚ filling the container to around three quarters of the way up‚ not covering the plant. In my case the plants I used were spinach sprouts‚ with two sprouts in each ice-cream container. A good idea I wasn’t aware of during my experiment is to poke holes in the bottom of the container and put them in larger containers to catch any excess water. Once the main part of the experiment is set up‚ use your record

Milgram’s experiment helped to share a different perspective on how people deal with these types of situations. It showed me that the average person would follow an order regardless of their personal beliefs as long as they were guaranteed that it was justified in some way shape or form‚ or otherwise reassured that the person they would supposedly be harming would make it through with their life intact and only sustain minimal if any damage. The Milgram experiment was a social experiment on the obedience

psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority. The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals. This experiment brought uproar amongst the psychological world and caused the code of ethics to be reviewed and ultimately changed. In the experiment subjects were asked to administer shocks ranging from fifteen volts

The Milgram experiment The Milgram experiment came about by a Yale University psychologist by the name of Stanley Milgram. The experiment was to test how well the study participants were and the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with what they thought was right. He concluded people obey either out of fear or out of a desire to appear cooperative even when acting against their own better judgment and desires. Stanley

In short‚ the experiment successfully supported the hypothesis. There was a significant disparity between the peanut food source and the sunflower seed food source. The ANOVA test was able to provide a p-value very close to 0 which means it’s statically significant. On top of that visually the average amount of the food source left was visually different when comparing 62.8 peanut grams left compared to 99 sunflower seed grams left. This clearly shows that peanuts are the more desirable food source

A lab experiment is a method of research that enables the researcher to control the environment. It is a way of doing a research in a controlled environment on a certain behaviour which will have a cause and effect. It is done in a controlled environment so that extraneous variables are prevented from affecting the results. Behaviourists use lab experiments because they are interested in a cause and effect of certain behaviours. The aim is to control all relevant variables except for one key variable
