Gravity

1 1. Name and describe five important steps in the formation of planets based on our current scientific understanding. a) Star and planet formation starts inside a collapsing cloud of gas and dust inside a bigger cloud called a nebula. Because of gravity pulling materials in the collapsing cloud closer together, the center of the cloud gets increasingly more compressed and because of this get hotter. The dense hot core of this collapsing cloud becomes the kernel of a new star. b) Next motions…

Inventor & Dreamer “Life is like riding a bicycle. To keep your balance you must keep moving” -- This is one of Albert Einstein’s quotes. Albert Einstein made a great impact on the world. He is credited with discovering a theory that found that gravity can affect time and space. He also made the atomic bomb when he was serving in the U.S. military to fight against the Germans in World War II (WWII) when he was getting targeted by Germany because he was Jewish, and the Germans were trying to…

Aristotle and his pupils, objects were attracted towards earth due to their innate properties instead of a downward-acting force. Thus, this was the interpretation of gravity during their time, and consequently their law of nature. Centuries later, scientists such as Galileo Galilei and Isaac Newton proved the existence of gravity and its tendency to attract objects, thus calling for a revision of the laws of nature as they…

Women who are interested in increasing their breast size should consider having a breast augmentation (breast implant surgery) with form-stable cohesive gel breast implants. The texture of these implants has led to their nickname, ‘gummy bear breast implants.’ Dr. Nina S. Naidu is one of the top plastic and reconstructive surgeons in the Bronx who frequently performs breast augmentation procedures with gummy bear implants. According to the most recent report released by the American Society of…

Introduction This case study report is to outline the process of planning an activity in science understanding physical science for a 5 year old child with the expectation of learning the concept of motion, inertia, force, velocity, acceleration and gravity by using balls, blocks and tubes. The report will also outline the pedagogy approach adopted by educators to ascertain that the child will engage in a physical science activity, which will improve the child’s skills of problem solving,…

still be acting on an object if its acceleration is zero. Acceleration is only the change in velocity and in the F=ma equation, the F stands for net force. For example, if a car was traveling at a constant velocity, it would still have forces such as gravity, friction, and normal force acting on it. 2. Only one force acts on an object. Can the object have zero acceleration? Can it have zero velocity? Explain. a. If only one force acts on the object, then the net force cannot be zero.…

equation which can be found by taking the derivative of the x equation, which we have done, and vel represents the velocity of the equation. g/2 represents the acceleration affecting the equation, which is gravity, and in represents the distance from the vertex to the origin. Notice that gravity had to be converted in order to keep all units consistent throughout the equation, shown in work. After plugging in the appropriate information, shown on work, we find the position x and position y…

Communication satellites, used for relaying anything from telephone signals, radio, and television signals, have been orbiting Earth since the first in 1962. Currently, there are more than 1,100 publically and privately owned active communication satellites in orbit with more than 2,600 inactive ones causing a significant amount of space debris. Importantly, communication satellites provide our security and our entertainment. At a high altitude of nearly 36,000km from Earth, the geosynchronous…

LENGTH -WEIGHT RELATIONSHIP AND CONDITION FACTOR 6.1. INTRODUCTION Length-weight relationship studies of fishes are considered as an important tool for understanding of fish. Length is a linear measure (in centimeter) and the weight of a fish (in gram) is approximately equal to its volume (cubic centimeter). Hence, weight of a fish is a function of length. The relationship can be expressed by the hypothetical…

Nothing happens by accident." - Chuck Knox. Even with a careful plan, Isaac Newton, the world-renowned scientist, was the founder of the theory of gravity. He was inspired when he was hit by an apple fallen from a tree and came up with an idea of gravitation. After that, he had to do large amounts of scientific calculation to prove his opinion and planned to express his idea in words. In other words…
