The key to making a concise mathematical definition of escape velocity is to consider the energy. if an object is launched at its escape velocity, what is the total mechanical energy etotal of the object at a very large (i. e., infinite) distance from the planet? follow the usual convention and take the gravitational potential energy to be zero at very large distances?

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
