Explain Newton's second law of motion with suitable example?

Image
Newton's second law of motion :                     According to this law,                                                    “ the force  acting  on a body is directly proportional to the rate  of change of linear momentum of the body  and the change in momentum takes place in  the direction of the force ”. This law helps us to measure the amount  of force. So, it is also called as ‘law of force’.  Let, ‘m’ be the mass of a moving body, moving  along a straight line with an initial speed ‘u’  After a time interval of ‘t’, the velocity of the  body changes to ‘v’ due to the impact of an  unbalanced external force F. Initial momentum of the body Pi = mu Final momentum of the body Pf = mv  Change in momentum          Δp =Pf–Pi...

CONTRIBUTION OF THE SCIENTISTS #2 Newton

NEWTON Nature and nature’s laws lay hid in night God said, “Let Newton be” and all was light. — Reads the epitaph for Sir Isaac Newton written by poet Alexander Pope. He discovered the Laws of Gravity and motion and invented the Calculus. But, Newton’s childhood did not give a clue to what was to come. He was a posthumous child, his father had died a few months before he was born. His father’s name was Isaac Newton as well. Newton senior was a farmer and could not even sign his name, according to sources. Junior was a premature baby and his mother said he could fit in a quart mug. She remarried before the boy turned three and so little Isaac was brought up by his grandmother. His stepfather died when Isaac was 10 and he moved in with the extended family of mother, grandmother and half-brothers and half-sister. Mother wanted him to take care of the estate, but Isaac was not interested. Thanks to an uncle, he was sent back to Free Grammar School to complete his education.Isaac entered Ca...

CONTRIBUTION OF THE SCIENTISTS #6 CURIE

Image
Marie Curie Marie Sklodowska Curie (1867 – 1934) was a Polish-born French scientist, who is one of the most famous women in the field of science. Her work on radioactivity paved the way for future scientific as well as medicinal advancements. Coming from a family of teachers, Marie deeply believed in the importance of a good education. She studied Physics and Mathematics at the Sorbonne University in Paris. Curie is most famous for her work on radioactivity along with her discovery of two radioactive elements, Radium and Polonium. Marie Curie often worked along with her husband, Pierre Curie, who unfortunately died in 1906 in a road accident. Curie is the first woman to have ever won a Nobel Prize and the only person till date to have won it twice in two different disciplines of science. Her contributions are not only limited in the laboratory and not many are aware of the important role she played in the First World War. Know more about her scientific accomplishments of Marie Curie th...
