Is kinetic energy and thermal energy the same thing?

'Internal' energy and 'Thermal' energy do not mean the same thing, but they are related. If you add Thermal Energy to a substance its Internal Energy will increase. Internal Energy is defined as the sum of the random distribution of the kinetic and potential energies of the molecules/atoms in a substance.

Also asked, is thermal energy kinetic energy?

Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat.

What is the difference between thermal and kinetic energy?

Thermal energy is the transfer of energy between two different bodies that have a temperature difference between them. Internal energy is the sum of the potential and the kinetic energy of the molecules of a substance.

What is the relationship between temperature and kinetic energy and thermal energy?

The short answer is that thermal energy is kinetic energy on the molecular level. Heat and temperature are proxy measurements for the motion of molecules. What we feel as heat is really energy being transferred to our bodies from molecules colliding against us.
