Composition of Concurrent Forces Abstract— The experiment aims to show the relationship of different forces acting at the same time by using different variables namely‚ the equilibrant force‚ the resultant‚ and the given forces Fa and Fb. The equilibrant force is the force that establishes equilibrium while the resultant is the addition of the given forces and is also the opposite of the equilibrant. The objective of the experiment is to determine the resultant of two forces experimentally‚ to

of the Western Electric Company (1924-32) as a basis to test his theories. These experiments were dubbed the Hawthorne Studies. It consisted of four main stages:- The illumination experiments The relay assembly experiments The interviewing programme The bank wiring observation room The illumination experiments focused on the effect of different intensity of lighting on the productivity. These experiments were however inconclusive‚ as the experimental groups production varied with no relation

Experimental design is a research method in which researcher tries to examine causal effects by manipulating independent variable under controlled settings and measures whether it produces any change to the dependent variable. In an experiment experimenter deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response. This differs from an observational study‚ which involves collecting and analyzing data without changing existing conditions. In an experimental

Effect of Clay in Soil on Plant Growth INTRODUCTION: In this experiment‚ the relationship between the amount of clay in the soil and plant growth was measured over a two week time period. The manipulated variable in the experiment was the amount of clay in the soil‚ specifically one hundred and twenty grams of clay mixed with eighty grams of soil‚ and the responding variable was the plant growth. Although clay in soil can be beneficial for plant growth in the sense that is provides good moisture

Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about each experiment: Experiment 1: Which method of finding the density give you the least percent error and why? Experiment 2: After completing the first experiment‚ answer this question. Which block do you think has the highest density and why?

the nineteenth century (reviewed in Deary et al.‚ (2011)). Beginning in 1865‚ F.C. Donders became interested if the time taken to perform basic mental processes could be measured. In his early experiments‚ Donders applied electric shocks to the right and left feet of his subjects. In one of his experiments‚ he did two trials with different conditions. In the first trial‚ subjects were not aware which foot will be shocked while in the second trial‚ subjects were aware. He found out the difference

To do so‚ I used an accidental sampling technique in order to gather 20 participants each of whom‚ I asked via email to take part in my experiment. I used this sample technique because there were no particular requirements to participate in my experiment. Thus‚ anyone was a “valid” candidate. I asked my participants to do an experiment on the internet created by certified trainers in micro-expressions and body language: Patryk and Kasia Wezowski. In their test‚ the participants had to

Immortal Life of Henrietta Lacks by Rebecca Skloot mentions animal experimentation. Different kinds of animals are used in many different experiments. Most experiments are used to help humans more than to help animals. Animal experimentation should not happen because most of the time‚ experiments can lead to animal cruelty. Cloning is one example of an experiment. The National Human Genome Research Institute wrote an article explaining cloning. Cloning is an interesting topic that does happen to be
