“Will You Please be Quiet‚ Please” is a short story collection that explores the human condition in the blue collar‚ working class citizens of the 1960’s in America. Carver is known not only for his minimalist style of writing‚ but also for his habit of basing many‚ if not all‚ of his stories on his own real life experiences. In this collection‚ Carver shows modern life as a series of hardships whereby ordinary people‚ who have the odds stacked against them‚ must battle for survival. He explores

the potential energy to hit the target cup. Energy is the ability to do work. Potential energy is the energy of position and kinetic energy is the energy of motion. In order for the ramp to be successful‚ the ramp had to have the right amount of potential and kinetic energy. If you have too much potential energy than the marble would have too much kinetic energy and the marble would not land inside of the target cup‚ it will go right over the top of it. If you have too little potential energy then

Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation. What am I going to do and what will it prove: I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’. Doing this will tell me the relationship between force‚ potential energy and kinetic energy. My Prediction:
