Momentum Lab Report Essays Momentum Lab Report Paper Momentum Lab Report Paper An exact determination of these forces is not practical but the presence of the forces can e allowed for by using a property known as the coefficient of restitution. The coefficient of restitution is the ratio of speeds of a falling object, from when it hits a given surface to when it leaves the surface. In laymans terms, the coefficient of restitution is a measure of bounciness. It basically is a property of collisions and depends upon the materials that are colliding. In this experiment, the coefficient of restitution between two balls, (a glass marble and a steel ball bearing) and the apparatus it is colliding with will be determined. AIMS To determine the coefficient of restitution between two balls, (a glass marble and steel ball bearing) and the apparatus it is colliding with. THEORY When two bodies collide, equal and opposite forces act on each body and will cause a motion. If there is no external force exerted to the system, then momentum will be conserved. Momentum is defined as (keg. M/s) and is a vector in the direction of v. (Newtons Second Law) equation (1) Impulse is defined I dot as which has useful applications in solving problems for forces when very short times are involved, such as during collisions. By taking the equation (1 ) for an integration, it shows that the impulse due to a Orca over a given time period is equal to the change in momentum as shown in equation (2). Equation (2) Figure 1 Consider the collision of the bodies in figure 1, there are equal and opposite forces (Newtons Third Law) acting on each body for the same amount of time during the collision. This condition can be represented mathematically as in equation (3). . Equation (3) Conservation of momentum tells that GIG + GO = 0 during a collision.

In 1960, United States encountered another enormous problem in the list of most illicit drugs, known as marijuana. Marijuana is enormously dangerous like the other drugs. It was newly introduced and very rapidly become popular and common among the drug addicts. After the people of the United States discovered this marijuana, all the government laws and prohibitions were forgotten and once again United States embarked upon the journey towards excessive drug abuse and addiction in the society. Even the common public, apart from the habitual drug addicts were then being attracted towards illegal drugs. This illegal business of drugs was becoming so popular that the government had to take serious steps towards the growing use of drugs. Hence, the government in the mid of the 20th century decided to take some serious actions against the people who were involved in promoting the drugs and also those who were using illegal drugs.

Provider- Patient Relationship (CASE) Essay Example | Topics and Well Written Essays - 500 words

Provider- Patient Relationship (CASE) - Essay Example How do health care professionals find the balance to make decisions that honor, both, patient confidentiality and other ethical obligations like reporting a potential crime. It is, often, not an easy decision to make. Imagine yourself as an E.R. physician and a patient arrives who has, according to his companions, ingested a large quantity of illegal drugs. He does not wish to be treated, however, his companions feel that he is mentally impaired by his drug use and should be treated regardless. It is absolutely true that while under the influence of intoxicants one may not be capable of the best possible judgment, however, that may not be true in every case. If one is capable of understanding the consequences of his or her decision regarding receiving treatment and the potential outcomes of refusing it then it would be unethical to disregard their personal choice not to receive medical care. In the case provided the patient was deemed capable of understanding the situation and was allowed to leave without receiving treatment. Ethically, however, if the patient had not been successful in being evaluated as capable of making his own decisions then treatment would and should be administered despite their objections, or at least until they achieve a more competent mental state; for example the effect of the drugs wears off. In the second scenario we are presented with a woman that has admitted to be unable to retrieve a condom filled with an illegal narcotic substance from her vagina. In this case the ethical decision required by the healthcare professional is not so easy. There is the health of the patient, but the patient’s potential medical condition was caused in the process of committing a crime. In this case the decision that seems to create amiable solution results from treating the patient, without contacting law enforcement, and then if drugs were

Understanding The House Made of Dawn by Scott Momaday Essay -- House M

Understanding The House Made of Dawn by Scott Momaday      Ã‚  Ã‚  In 1969, N. Scott Momaday became the first Native American to win the Pulitzer Prize in the area of Letters, Drama, and Music for best Fiction.   As Schubnell relates in N. Scott Momaday: The Cultural and Literary Background, Momaday initially could not believe that he had won a prize for a work that began as a poem (93).   Schubnell cites one juror who explains his reasoning for selecting House Made of Dawn as being the work's 'eloquence and intensity of feeling, its freshness of vision and subject, [and] its immediacy of theme' (93).   For these reasons and many more, House Made of Dawn hailed the arrival on the American literary scene of a "matured, sophisticated literary artist from the original Americans" (Schubnell, 93).      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There are many elements influencing and incorporated into House Made of Dawn that the reader will better appreciate by gaining an understanding of their history or significance in Native tradition. Louis Owens's suggests in his work Mixedblood Messages that "before discussing any aspect of Native American literature, it is important to know what literature we are talking about" (15).   Thus, before one evaluates or analyzes House Made of Dawn any further, one should attain knowledge of the author and culture.   Also, it will be prudent for the reader to have background knowledge of such elements as stories and running.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Momaday's life greatly affects aspects of House Made of Dawn.   Navarro Scotte Mammedaty, a mixedblood of Kiowa and Cherokee descent, (as well as European ancestry on his mother's side) was born on February 27, 1934.   Numerous scholars and critics note that from the beginni... ...seems the more one knows, about Momaday, the Kiowa, the Navajo, and people of Jemez, among other things, the more one grasps the full meaning of House Made of Dawn.   It is a work full of possibility and revelations.

Rebellion in The Handmaids Tale by Margaret Atwood Essay

Rebellion in The Handmaids Tale by Margaret Atwood Rebel is a term, which is highly weighed down with emotion. In society today we perceive a rebel to be a figure opposing a much stronger majority. We distinguish the rebel to be a character who fights for his/her own ideals. We see a person that will do anything almost being ruthless to destroy the boundaries set up against him/her by the stronger mass. We witness the rebel as an individual who deliberately defines a battlefield and two fighting fronts. The rebel is constantly is resisting.

Radiation and chemicals have contaminated the physical world in which this society dwells. As a result the fertility rate has drastically reduced the fertility rate. The government has introd uced handmaids, who are young fertile females whose job is to act as surrogate mothers. They basically are wombs on two legs. If they fail to conceive three times, they guaranteed death by working at the colonies. The reader follows the life of a handmaid called Offred. We witness how Offred distances herself from the system day to day. Our protagonist Offred is a character, which we can easily categorise. It is hard to perceive Offred as a rebel. However if Offred is at all to be labelled a rebel she must belong to the class of rebels that act passively. During the novel there are only a small number of occasions where Offred acts actively. There is great contrast set up by Atwood to emphasise Offreds inert behaviour. Atwood presents to us the character called Moira. Moira is Offreds best friend. I feel that I recognise Moira to be the active rebel. Moira is the one who goes on demonstrations. Moira is the one who from the first step into the red centre wants to leave it.
