On July 20‚ 1969‚ Astronauts Edwin “Buzz” Aldrin and Neil Armstrong of Apollo 11 landed on the moon. A few years later on December 14‚ 1972‚ the astronauts of Apollo 17 became the last manned mission to the moon. It seems inconceivable that 43 years later‚ these footprints left by Apollo 17 astronauts were the last of any man. Even more disturbing is the lack of a permanent commemoration or memorial to the accomplishment of those 12 astronauts that made the perilous journey. With all of the

gravitational forces of the sun and moon. All physical objects attract each other with gravity‚ but the strength of the force depends upon the mass and distance of the objects. The shorter the distance or greater the mass‚ the stronger the gravity. Both the sun and moon have gravitational pulls on the Earth‚ but the strength of the moon’s pull is stronger than the sun’s because it is much closer to the Earth. The moon pulls the ocean water on the side of the Earth facing the moon more strongly than it pulls

1960’s Vietnam War. Beatles. John F. Kennedy assassinated in 1963. First moon landing. Anti-war movement. Hippies. Revolution in social norms‚ clothing‚ music and drugs. The 1960’s were a pretty crazy ten years from the brutal Vietnam war to the popular rock band known as the Beatles. During this time there was a lot of ups and downs but it now goes down as a crucial time period for the United States. When you of the 1960’s the first thing that pops into many people’s head is the Vietnam

Introduction "Gravity is a force of attraction that exists between any two masses‚ any two bodies‚ any two particles. Gravity is not just the attraction between objects and the Earth. It is the attraction that exists between all objects". (NASA gravity 2000) Gravity is a very essential part of life on earth. We are in the exact position in the sun’s gravitational field to keep us in orbit and keep life ongoing on our planet. Gravity is a downward force on any body of mass‚ the larger the mass of

First‚ I will explain how the actions of the USSR started The Space Race. Next‚ how the United States developed NASA and eventually landed the first man on the moon. Finally‚ the technologies that were developed for space travel and have now become household items we all use in everyday life. In the 1950’s‚ America was in an upswing. After the victory in WWll‚ the economy was rapidly expanding‚ the baby boom had begun and Levittown was built as an example of suburban living. In a different part

7.1 Newton’s Law of Universal Gravitation Newton’s Law of Universal Gravitation states that: Every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Consider two particles of masses m1 and m2 separated by a distance r. Each will exert a force F on the other‚ given by where F : gravitational force between the two particles. m1‚ m2 : masses of the

Neil Armstrong Background Neil Armstrong was born in Wapakoneta‚ Ohio in the year 1930. His services as a pilot were called upon during the Korean War. Shortly after graduating from Purdue University in 1955‚ Armstrong joined the National Aeronautics and Space Administration‚ then known as the National Advisory Committee for Aeronautics. At the time the functions of the N.A.C. were to plan‚ direct‚ and conduct all United States aeronautical and space activities‚ except for those that

I’d like you to imagine a snail. Imagine how it looks; how it moves; how it feeds. Chances are the mental image you conjured up wasn’t too flattering. And who could blame you: snails are slimy and gross. Despite this repulsion‚ I find myself wondering‚ like the high school english teacher trying to grade the “artsy” kid’s creative writing piece; “What‚ in the hell‚ does this ugly thing mean?”. The idea of the snail has captivated my attention in a way that its physical counterpart never could. I

between the Earth‚ the moon and the shadow during lunar eclipses. When an object passes in the course of another object’s shadow is when eclipses happen. Any kind of shadow consists of two parts. First is the umbra which is region of total shadow while the penumbra is the external region of partial shadow. Compared to the moon‚ the Earth’s shadow is very big. Since the shadow is very big this can cause a total lunar eclipse to last about 1 hour and 45 minutes. For example the moon passes through the
