Energy

mechanical energy includes kinetic and potential energy, and thermal energy includes only kinetic energy

mechanical energy is a property of whole objects, and thermal energy is a property of the particles that make up an object

mechanical energy includes kinetic energy only, and thermal energy includes kinetic and potential energy

mechanical energy applies only to objects that are moving, and thermal energy applies only to objects at rest

thermal energy

the molecules in beaker A are moving faster than the molecules in beaker B

the molecules in beaker A are moving at the same speed as the molecules in beaker B

the molecules in beaker B are moving faster than the molecules in beaker A

beaker A contains more molecules that are moving than beaker B does

the total kinetic energy of the particles in an object

the movement of thermal energy from a warmer object to a cooler object

the expansion of an object due to increased thermal energy

the difference in temperature between two objects
