Thermal energy is the internal energy present in a system due to the random motions of its particles. It is the total kinetic energy of the particles in a substance. This energy is associated with the temperature of the substance and is a measure of the average kinetic energy of the particles.

1. **Energy generated by the motion of objects**: This statement is partially correct. Thermal energy is indeed related to the motion of particles, but it specifically refers to the random, microscopic motion of particles within a substance, not the macroscopic motion of objects.

2. **Transfer of energy from a hot object to a less hot (colder) object**: This describes the process of heat transfer, not thermal energy itself. Heat is the energy transferred between objects due to a temperature difference.

3. **The sun providing heat to the Earth through radiation**: This is an example of heat transfer via radiation. The sun emits energy that travels through space and warms the Earth, but this is a process of heat transfer, not a definition of thermal energy.

In summary, thermal energy is the total kinetic energy of the particles in a substance due to their random motion.
