Maria is at the playground and swinging on the swing set. At the top of her swing, she has 500 Joules of Potential Energy (PE). At the bottom of her swing, she has 1000 Joules of Kinetic Energy (KE). What is Maria's Mechanical Energy (ME)? ME= PE + KE * 500 J
5 J
500,000 J
1500 J

[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.
