its speed reduced due to the gravitation pull of the star‚ and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the sun light would not be able to escape and therefore be invisible. [2] Karl Schwarzchild was a German astrophysicist who used Einstein’s theory of relativity to compute and calculate the gravitation fields of stars. His solution

Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

In June 1661‚ Newton left Woolsthorpe to enroll at Cambridge University. This incredible man was deeply engrossed in private study during his undergraduate years‚ and developed his first theories in calculus‚ optics‚ and the law of gravitation. Newton’s first major public scientific achievement was designing and constructing a reflective telescope in 1668. Newton’s became a professor at Cambridge and was required to deliver an annual course of lectures and chose his initial topic to be

scientist since Sir Isaac Newton to our modern vision of physical reality‚ is clearly one of the most gifted intellects the world has ever known. In a relatively brief period of time‚ Einstein changed the way people thought about space‚ time‚ gravitation and war. Albert Einstein was born on March 15‚ 1879‚ in the southern Germany city Ulm. Both of Einstein’s parents were Jewish‚ although they did not strictly practice the religion. As a adolescent he was very dull‚ in fact his parents first

• Intramuros Intramuros is located along the southern bank of the Pasig River. It was built by the Spaniards in the 16th century and is the oldest district of the city of Manila‚ the capital of the Philippines. Its name‚ in Spanish‚ literally means “within the walls”‚ meaning within the wall enclosure of the city/fortress. During the Spanish colonial period‚ Intramuros was considered Manila itself. The site of Intramuros was originally a large Malayan-Islamic settlement named “Maynilad”‚ ruled

According to Isaac Newton’s law of Universal Gravitation‚ objects near the surface of the earth accelerate at a rate of 9.8m/s/s towards the ground. The purpose of this investigation was to determine the relationship between the angle of inclination and the acceleration of a physics cart. This was

Newton‚ born soon after Galileo‚ creates the three laws dictating motion and laws called Newton’s Law of Universal Gravitation. Upon discovering the law of universal gravitation‚ Newton invents calculus‚ a type of math‚ for use in his studies. Newton’s knowledge is crucial in the understanding of gravity for modern physics. Albert Einstein‚ a key figure in modern physics‚ develops and publishes

Johannes Kepler was born on December 27‚ 1571 in Weil der Stadt‚ Germany to parents Heinrich and Katharina Kepler . From a very young age‚ Johannes faced countless amounts of struggles‚ most notably the death of his father at the tender age of five. In addition to this tragedy‚ Kepler had crippled hands and impaired eyesight‚ due to his bad health. Despite his physically damaged self‚ Kepler was able to thrive cognitively. He could solve any problem with numbers and questioned everything‚ the habit

1. Right ascension and also declination is just like longitude and latitude because they are all used for specific location purposes. As people on the ground use longitude and latitude to find things on earth‚ scientists and astronomers use right ascension and declination to find things in the sky. 2. The North Pole is north 90 degrees latitude and the South Pole is south 90 degrees latitude. There is no longitude for either the south or North Pole because neither one can be given a value.
