In Chapter 14, kinetics of particle, work and energy, we could summary this chapter explain us about the moving particle based on the principle of energy that involves force (F), velocity (v) and displacement (s). By these kinds of units, we could solve the problems that involve power (P) and efficiency (ε). In this chapter also explained us about conservation of force and theory of conservation of energy due to solve the problems of kinetic energy. While in Chapter 18, kinetics of rigid, work and energy, we could summary this chapter almost got the same explanation by the chapter 14 which was it contain about work of force, kinetic energy, gravitational potential energy, elastic potential energy, conservation of energy and principle of work and energy. If we study deeply about these two chapters, we could get the similarities and differences about the work and energy by the …show more content…

Kinetics of particle was means the particle that moving freely in the certain displacement and force direction. While the kinetics of rigid body means the moving thing that connected to another thing in the certain angle and force direction. Firstly, in due the work of force by the kinetics of particle that moving along a finite was determined by integration, U=∫_1^2▒〖F cos⁡θ 〗 ds while in work of force by the kinetics of rigid body that moving in a finite angle was determined by the another integration, U=∫_(θ_1)^(θ_2)▒M dθ which it calculated the value of moment. Then, an another different was in Chapter 14, the kinetics of particle was use the original equation to determine its energy, T=1/2 mv^2 while in Chapter 18, the kinetics of particle was use the new derived equation, T=1/2 〖I_IC ω〗^2 which it came from the equation of T=1/2 〖mv_G〗^2+1/2 〖I_G ω〗^2 that was involved the value of angular velocity (ω) and mass center velocity

Chapter Three Summary Slater introduces chapter three with telling us that David Rosenhan was greatly ill towards the end of his life. Slater later tells us that Rosenhan and eight of his friends fake they’re way into different mental hospitals just by saying “I’m hearing things”. In fact, Slater wanted to see how the psychiatrist can see the sane from insane. Later, Robert Spitzer gave Rosenhan rude criticism about his experiment.

Kinetic theory states that molecules are always in constant motion. Kinetic energy and molecule velocity increases as temperature increases. Reactions require collisions between reactant molecules or atoms. In chemical reactions, the reactants change into products when molecule collide with enough energy to break old bonds to make new ones. Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered.

When working in the science fields there are many obstacles a person of faith may face. The biggest of these is the controversy over the concept of evolution and how the world came into being. Atheists and evolutionists are always trying to find ways to disprove God with science. However, after spending several years learning about how nature and chemicals work together to form our world it is hard for me to imagine that all of it came into existence without a creator.

Forty-three years later, Roe v. Wade continues to be one of the most, if not the most, controversial decisions made by the United States Supreme Court. It is a very hot button issue in politics, with republicans usually disagreeing with the decision and democrats supporting it. Then there are many people in the middle, some who support abortion but want more restrictions such as how far into her pregnancy a woman can terminate or others who want abortion to be illegal, but want exceptions for certain cases, such as rape, incest, or when the mother’s life is in danger. Liberals says women should have complete control and say over their own body, and conservatives say that a fetus is a human life from the moment of conception, and therefore should

Animals and plants become at risk for extinction, or endangerment, when environments and ecosystems are changed by human activities or other natural causes (Wright & Boorse, 2014). Regrettably, human activity is usually the source of environmental change and endangerment to a species through pollution, over-consumption, and in some regions of the world, over-population (Wright & Boorse, 2014). Also attributable to the destruction of a species, are the human activities that result in habitat loss and the introduction of an exotic species into foreign ecosystems (Wright & Boorse, 2014). Human activity is not solely to blame, as each species also has natural predators; however, habitat loss, relating to economic development, appears to be the

The first law states that a moving object will remain in motion and a resting object will remain at rest until changes by an unbalanced force. The second law of motion says that the greater the mass of an object, the more force is needed to acceralte it. According to Newton’s third law of motion, there is always an equal and opposite re-action that occurs as an effect of every action. Isaac Newton’s laws of motion are important in the world of physcs because they are accurate, relate to almost everything that we experience in our daily lives, and tell us how things
