Acceleration, in physics, is the rate at which the velocity of an object changes over time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law. [1] The SI unit for acceleration is the metre per second squared (m/s2). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law.[2][3] As a vector, the calculated net force is equal to the product of the object's mass (a scalar quantity) and the acceleration.
For example, when a car starts from a standstill (zero relative velocity) and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the car changes direction there is an acceleration toward the new direction. When accelerating forward, passengers in the car experience a force pushing them back into their seats. They experience sideways forces when changing direction. If the speed of the car decreases, this is acceleration in the opposite direction, sometimes called deceleration.[4]Mathematically, there is no separate formula for deceleration, as both are changes in velocity.

In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity.[1] The average speed of an object in an interval of time is the distance travelled by the object divided by theduration of the interval;[2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
Like velocity, speed has the dimensions of a length divided by a time; the SI unit of speed is the metre per second, but the most usual unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.

...THE DAY THEY BURNED THE BOOKS by Jean Rhys - Dominica Source: Tigers Are Better-Looking (1960s, collection of stories). My friend Eddie was a small, thin boy. You could see the blue veins in his wrists and temples. People said that he had consumption and wasn't long for this world. I loved, but sometimes despised him. His father, Mr Sawyer, was a strange man. Nobody could make out what he was doing in our part of the world at all. He was not a planter or a doctor or a lawyer or a banker. He didn't keep a store. He wasn't a schoolmaster or a government official. He wasn't — that was the point — a gentleman. We had several resident romantics who had fallen in love with the moon on the Caribees — they were all gentlemen and quite unlike Mr Sawyer who hadn't an 'h' in his composition. Besides, he detested the moon and everything else about the Caribbean and he didn't mind telling you so. He was agent for a small steamship line which in those days linked up Venezuela and Trinidad with the smaller islands, but he couldn't make much out of that. He must have a private income, people decided, but they never decided why he had chosen to settle in a place he didn't like and to marry a coloured woman. Though a decent, respectable, nicely educated coloured woman, mind you. Mrs Sawyer must have been very pretty once but, what with one thing and another, that was in days gone by. When Mr Sawyer was drunk — this often happened — he used to be very rude to her. She never answered...

Maya Angelou

...boyfriend. Maya told her family and that man was put in jail for only one day. He was beaten to death a few days after being released from jail, which caused her to become mute for almost 5 years. I think that with everything Maya Angelou has been through, so far in her life, if she was not a strong enough person, she probably would have drowned herself in sorrow and punished herself for all that has happened in her life. Instead, she moved back to Stamps, where her grandmother lived, and began to meet with Ms. Bertha Flowers, who was a family friend and teacher. Ms. Flowers helped Maya with literature, art, and managed to help Maya find her voice again. When Maya hit thirteen years of age, she decided to reunite with her mother in San Francisco. She attended high school and worked very hard. She also received a scholarship to study dance and drama at the California Labor School. Maya had to drop out of high school to become San Francisco’s first female, African-American streetcar conductor. Finally, she returned to school, even though she was pregnant, and still managed to graduate high school. At seventeen, Maya was a single mother, who worked numerous jobs, such as, being a cook, waitressing, and even prostituting, just to be able to support herself and her son. Once again, I feel that in order to be able to make it through high school while being pregnant, is a very challenging task to complete. Apparently, Maya Angelou was...

Poem Maya Angelou Still I Rise and song Collective Soul December showing the effects of the individual through positive and negative expression. Poetry Maya Angelou and Collective Soul are similar in some respects, when broken down correctly. Collective Soul wrote "Why drink the water from my hand contagious as you think I am?"; reflects the same idea that the actions of Maya Angelou when she said, "Are you annoyed by my boldness Why did you suffer from sadness"; These two parts of his writings to make a similar question.

I Know Why the Caged Bird Sings

...I know Why the Caged Bird Sings is an autobiographical account of Maya Angelou that demonstrates how love for literature and having a strong character can play a significant role in overcoming racism and distress. In the course of the story, it is evident that Maya changes from being a casualty of racism to become a young woman with self-dignity and identity that helps her to overcome prejudice. The context of I Know Why the Caged Bird Sings focuses on the problems associated with racism that was prevalent in the southern states. Racist oppression is a common theme in the book that is portrayed by all the major characters; in fact, all the other themes in the book are closely related to racism, identity and segregation. In addition, the style and genre, and the structure of this literary work make significant contributions towards its thematic development, which focus on resistance to racism, the significance of the family, self-identity and definition and independence. Walker (95) argues that I Know Why the Cage Bird Sings is characterized by thematic unity, which is achieved using the structure adopted in the text that takes more of a thematic form rather than a chronological form. In addition, Angelou managed to emphasize on the universal ideas in her literary work irrespective of its periodic quality. In I Know Why the Caged Bird Sings, Maya Angelou used the major characters of the book to facilitate its thematic development identity, racism and literacy throughout the text...

Maya Angelou Influences

...for music. Once she published an album, Miss Calypso, she realized that she loved writing more than music and theatre. With a shift in her career, Maya devoted all of her time to become a better writer and poet. A little while after Martin Luther King Jr. passed away, she was confronted by many publishers who wanted her to write an autobiography after hearing about her interesting life. She took up the challenge, and that memoir became her first published piece of writing: I Know Why the Caged Bird Sings. With such a painful and horrible childhood, Maya Angelou did what most people could not do: she took the good out of it. Instead of wallowing over the negativity, she took everything that happened to her and used it for inspiration for writing. Maya went through the worst; she was poor, African-American, raped, kept silent, and young, which made a powerful memoir that readers could sympathize with. They were not only touched by the pain she experienced, but were also inspired by how she overcame everything thrown in her path. Everybody could relate to her emotions, and she was a clear reminder to suffering people that they were not alone. Patricia Rosier summed it up well. “She was not afraid to fiercely explore her self-identity so that we, too, could fully be who we are” (“Angelou’s Cultural impact”). Maya spun a beautiful web out of the dust she was left in, and her compelling voice, in writing and speech, touched the lives of many. In her collection of autobiographies, Maya...

...Sarah Liette Coach 6-8-2015 Maya Angelou “Graduation” Summary Graduation Graduation is an important transition time in every person’s life. It is about moving on to something better and more important and to use your knowledge to achieve life goals. This is what the children attending the grammar school believed as well, including Maya Angelou. Given from her point of view, the story Graduation has ethos because as an African American girl, she shared the same thoughts and feelings as everyone standing on the stage or in the auditorium when Mr. Edward Donleavy passively demeaned everything the students had worked so hard to achieve. This story is told by a women who had surpassed all of the difficulties in life to get to this day, and through her learned, and personal, figurative, and detailed writing, has been able to pass on both the ill feelings and the warm feelings of that experience from Mr. Donleavy’s speech, to that of Henry Reed. What Angelou does best is evoke feelings and empathy from her readers. By relating to them and broadcasting her emotions for everyone to see, she emphasizes her sense of being wronged. When she is describing the excitement and anxiety in the people around her, she is relating to what everyone feels when they are about to graduate. “The children in Stamps trembled visibly with anticipation...the whole young population had come down with graduation epidemic.” (22).

Adversity in I Know Why the Caged Bird Sings

...Throughout "I know why the caged bird sings", Maya Angelou portrays her experiences with adversity, as well as the experiences of many others, how she copes with them and how she rises above them. Maya exposes the reality of adversity in all its forms and by the end of the novel we are able to learn what overcoming adversity truly means. One of the social issues seen is that Maya is not getting the attention she needs from her caregivers. The author uses literary devices to explore the issue when she says "she was like a pretty kite that floated just above my head. If I liked I could pull her to me by saying I had to go to the toilet or by starting a fight with Bailey." This simile helps to show that Maya's mother takes care of her basic needs but fails to give her the actual care and attention a child needs. The issue contributes to the text as a whole by demonstrating how Maya might act in certain situations. An example of this is when she liked the attention she was getting from Mr. Freeman at first, although she knew it wasn't right. Overcoming this adversity helped Maya to grow as a person and become more independent. As Maya goes through life she often encounters racism such as when she gets a toothache and Momma takes her to the white dentist. During this time we are able to see discrimination against blacks come to life in front of Maya. The quote "Annie, my policy is that I'd rather stick my hand in a dog's mouth than in a nigger's." is used to portray the discrimination...
