ANALYSIS Physics is not all about the Resolution of Forces and Kinematics. One of the topic in Physics is Projectile Motion. Projectile Motion is a special case of two-dimensional motion. Gravity is the only considered external force acting on it while an object is airborne. Projectile is the moving body in this kind of motion. It refers to any object thrown‚ launched or otherwise projected so that once released‚ if air resistance is neglected‚ its path is affected only by the Earth’s gravity. As

the jumping short distance in increased. It is advised that we slightly reduce the velocity to enhance accuracy. Accuracy can also be enhanced by reducing the height of release. To reduce velocity the following concepts of physics in the area of kinematics should be taken into consideration. Displacement: the distance between the ball release and the basket goal. Time: the total time in seconds that the ball should take to get from the release point to the basket goal. Velocity: Should be slightly

Galileo Galilei Galileo was born in Pisa (then part of the Duchy of Florence)‚ Italy‚ the first of six children of Vincenzo Galilei‚ a famous lutenist‚ composer‚ and music theorist; and Giulia Ammannati. Galileo became an accomplished lutenist himself and would have learned early from his father a healthy scepticism for established authority‚[15] the value of well-measured or quantified experimentation‚ an appreciation for a periodic or musical measure of time or rhythm‚ as well as the illuminative

manufacture‚ and application. Robotics requires a knowledge of electronics‚ mechanics and software‚ and is usually accompanied by a large working knowledge of many subjects. The structure of a robot is mostly mechanical and can be called a kinematic chain. This is functionality being similar to the skeleton of the human body‚ so “The chain is formed of its bones‚ muscles and joints which can allow one or more degrees of freedom” (Smith16). Scientists develop man-made mechanical devices

Technology is determined by need. Inventors often have a mysterious skill of resolving situations with their modernisms. But the thing that splits engineers from ordinary innovators is the ability to distinguish the importance of maintainable technological solutions for the future. Although many of our needs and difficulties remain the same‚ the answers keep changing with time. Furthermore to finding out how a machine operates‚ I’ve always been interested in design aspects and observing the incipient

Re = Reynolds number V = Fluid velocity (m/s) d = Pipe diameter (0.012m) v = Kinematic viscosity (0.893 x 10-6m2/s) Laminar Flow‚ Re < 2000 Laminar flow denotes a steady condition where all stream lines follow parallel paths. Under this condition‚ the dye will remain easily identifiable as a solid core. Transitional Flow
