Detailed explanation-1: -Thermal energy is the sum of the kinetic and potential energy of all the particles in an object. The figure shows that if either potential or kinetic energy increases, thermal energy increases. Kinetic energy increases. Potential energy increases.

Detailed explanation-2: -The total kinetic energy of moving particles of matter is called thermal energy. The thermal energy of matter depends on how fast its particles are moving on average, which is measured by temperature, and also on how many particles there are, which is measured by mass.

Detailed explanation-3: -Thermal energy pertains to the kinetic energy of the molecules within an object. Heat is the transfer of energy between two objects.

Detailed explanation-4: -The sum of an object’s potential and kinetic energies is called the object’s mechanical energy.
