EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

The Holy experiment William Penn holy experiment is to create a colony on the principle of self-government‚ religious toleration‚ and brotherly love. William Penn make a government which can run with the law of the people. Pennsylvania first constitution organized the government into three parts: the governor‚ the seventy two member of provisional council‚ and general assembly with two hundred member. While the proprietor held his office by hereditary‚ the council and assembly were elected by the

Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

Conflicting Claims About the Effect of Exercise on the Rate of Clothespin Squeezing * Hypothesis: If a person does not exercise before to squeeze a clothespin‚ then they will be able to squeeze the clothespin more times in a minute than if they do exercise first. Without exercise the person will have more energy to squeeze the clothespin more times than the other who exercises first and might get tired more rapidly. * Materials: * Clothespin * Stop watch * Pen or Pencil

The scientific method is a method for conducting an objective investigation. The scientific method involves making observations and conducting an experiment to test a hypothesis. The number of steps of the scientific method isn’t standard. Some texts and instructors break up the scientific method into more or fewer steps. Some people start listing steps with the hypothesis‚ but since a hypothesis is based on observations (even if they aren’t formal)‚ the hypothesis usually is considered to be the

changes and thus the community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration
