The swimmers while swim in the swimming pools are not facing identical and constant environment‚ where they could perform according to their merits. Theses swimmers are facing vague gravitational forces‚ which becomes advantageous to some and disadvantageous for others depending upon their swimming lane positions in the swimming pool while swimming. This study is based on scientific principles of gravitational physics for the benefit of swimmers world over‚ so that they could be given equal opportunity

Abstract In this experiment Newton’s Second Law of Motion was measured with the use of the gravitational acceleration g on Earth by applying a free fall process. Objective The objective of this experiment is to validate Newton’s Second Law of motion. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time. Procedure First‚ measurements were taken of the distance from the stairway

Earth could be a consequence of the gravitational force‚ because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth. This can be illustrated with the thought experiment shown in the following figure. Suppose we fire a cannon horizontally from a high mountain; the projectile will eventually fall to earth‚ as indicated by the shortest trajectory in the figure‚ because of the gravitational force directed toward the center

objects on earth. Believing that gravitational forces were responsible for each‚ Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth’s center from the object’s center. But distance is not the only variable affecting the magnitude of a gravitational force. Consider Newton’s famous

Stage 6 – Yr 12 Notes 9.2 Space: Context 1 – The Earth has a gravitational field that exerts a force on objects both on it and around it. Define weight as the force on an object due to a gravitational field Mass (m): • The amount of matter in a body • Constant anywhere in the universe • Scalar quantity • Measured in Kilograms (Kg) Weight (W): • The force acting on an object due to a gravitational field • Attractive force • Vector quantity • Direction
