A mass is suspended vertically from an ideal spring. When the action in this problem begins, the mass has been lifted upwards so that the spring is much less extended than when the mass is simply hanging, at rest, from the end of the spring. The mass is then released; it falls and stretches the spring and ends up vibrating up and down about the equilibrium position (the position where the total force on the mass is zero).A) The acceleration of the mass (as well as the net force on the mass) is greatest in magnitude and is directed upward when the spring is least extended (i. e. the mass is at the upper endpoint of the motion).the spring is most extended (i. e. the mass is at the lower endpoint of the motion). The mass is somewhere between the equilibrium position and the lower endpoint of the motion. The mass is passing the equilibrium position. B) The speed of the mass is greatest when the spring is most extended (i. e. the mass is at the lower endpoint of the motion).the mass is passing the equilibrium position. The mass is somewhere between the equilibrium position and the lower endpoint of the motion. The spring is least extended (i. e. the mass is at the upper endpoint of the motion).C) The acceleration of the mass is zero when the mass is passing the equilibrium position. the spring is least extended (i. e. the mass is at the upper endpoint of the motion). The mass is somewhere between the equilibrium position and the lower endpoint of the motion. The spring is most extended (i. e. the mass is at the lower endpoint of the motion).D) The acceleration of the mass (as well as the net force on the mass) is greatest in magnitude and directed downward when the mass is passing the equilibrium position. the spring is most extended (i. e. the mass is at the lower endpoint of the motion). The spring is least extended (i. e. the mass is at the upper endpoint of the motion). The mass is somewhere between the equilibrium position and the lower endpoint of the motion.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
