bingo! Our machine had multiple transfers of energy which consisted of both kinetic and potential energy. Overall‚ our machine displays eight simple machines that all consist of transfers of energy in the process. To begin‚ our contraception begins by placing a ball into a bingo spinner. Before the ball is placed into the spinner the ball has potential energy‚ but as soon as it is dropped the potential energy transfers to kinetic energy due to the ball spinning in the wheel. Next‚ the ball rolls

positional energy. As the roller coaster falls is has enough kinetic energy to make it through the remainder of the ride. Inertia keeps the object in motion. The other forces bring the roller coaster to a stop by friction. Since roll coasters don’t have motors they need to be pulled up by a chain up the first big hill. No engine is required because of inertia. The roller coaster won’t last forever. Two of the significant energies are friction

Running head: ROLLER COASTERS Roller Coasters: History‚ Physics‚ and records Abstract This paper explains the early history of roller coasters from their rough beginnings in Russia through the migration to the United States. It goes on to emphasize the important physics that go along with how roller coasters operate and the forces that work with and against it. In the end it talks about what records and accomplishments have been made with the usage of roller coasters. Formal Outline I

OBJECTIVE The purpose of this experiment is to calculate the gravitational potential energy through experimental values‚ to calculate the theoretical potential energy given the experimental kinetic energy in an isolated system while also using the kinetic energy to find the spring constant‚ and to compare kinetic energies and potential energies in an isolated system to see if they are equivalent. METHOD To calculate the gravitational potential energy through experimental values‚ we dropped a

of pitot tubes: Pitot tubes‚ Static tubes‚ and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°‚ with an open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant since there is no direct opening at the other end for it to exit from. As the inert fluid rises‚ it creates a pressure of its own. This pressure is equivalent to the dynamic pressure‚ which can be seen as the kinetic energy of the fluid per unit

Sports Mechanics Of Tennis The hitting and subsequent motion of a tennis ball in playing a forehand topspin Abstract The forehand topspin is one of the primary techniques that is utilised in modern day tennis. It has been used to enhance a player’s overall forehand skills that result in the maximising of a players groundstroke power output. This report will analyse the motions the tennis player and tennis ball undergo‚ the forces acting on the player and the ball and lastly‚ the force transformation
