In terms of physic, the airplane is staying afloat because it is trading potential energy for kinetic energy, which equals velocity. As the gliders lose altitude, they convert potential energy into kinetic energy, which keeps the plane in motion. This is an example of the conservation of energy because most of the potential energy is converted into kinetic energy and no energy is lost. ...

Direct proof remains that energy is vanishing from volumes of space without a trace. ... This leakage does not violate the law of conservation of mass-energy because the heat energy is incorporated into the mass of the hole. ... Electrons furnish photons at lower energies, such as x-rays. ... Because the objects are moving at close to the speed of light, the kinetic energy available for transformation into heat is comparable to the energy inherent to their mass at rest. ... In this sense, black holes transform rest mass into thermal energy. ...

Conservation of Momentum Assumptions: • Deceleration is constant. ... Energy Equation Using the energy equation we can iteratively find the velocity of the submarine Assumptions • Horizontal Travel • Steady flow eq(1) Assume V=1m/s and iterate to find friction factor f this tells us that flow is turbulent With this Reynolds number and an =.000039 we use the Moody chart to find friction fractor f=.0235. ... Also from the loss terms in the energy equation we can calculate the head loss due to pipe length and diameter and the loss due to t...

Have you ever wondered how car manufacturers descide how much of each reactant to put into an airbag? How the government controls pollution? How about how reactant proportions role play in engine efficiency? In this essay, I will explain the history of stoichiometry, its practical uses, and I will ...
