Kinetic energy is the energy of motion. It can be used interchangeably with the word temperature. Which line segment(s) show an increase in kinetic energy? Answer: Solid; Liquid; Gas; Explanation: From the given illustration, temperature increases at line segments Solid, Liquid, Gas. Thus, the kinetic energy in Solid, Liquid, Gas also increases. WebRead the description and indicate whether the object gained energy (positive work) or lost energy (negative work). (NOTE: If this is part is difficult, review the section on work.) Then, indicate whether the gain or loss of energy resulted in a change in the object's kinetic energy, potential energy, or both.

WebMar 31, 2024 · Yes, internal forces within the system (gravity is an internal force within the ball/Earth-system). "as a result it is the negative of the work done by external conservative forces." Yes, and the reason is pretty obvious: the potential energy only exists because the conservative force (like gravity) pulls. WebA favorable reaction is one in which the change in free energy ∆G° is negative ... then the product formed is one lying across the smaller energy barrier. This is called kinetic control and the ratio of the products formed depends on the relative energy barriers leading to the products. Relative stabilities of the products do not matter.
