Heat is thermal energy moving from one substance to another.
a stove top heating up a pot of boiling water
ROUGHLY SPEAKING, that would be thermal energy.
- How fast the particles are moving - The number of particles in a substance
Thermal energy (temperature) is the measurement of kinetic energy of atoms moving in a substance, therefore, as the speed (kinetic energy) of these atoms increases, thermal energy increases as well.
Thermal energy at the molecular level is a reflection of how fast their random motion and how "agitated" they might appear were you able to view them. In more detailed terms their nett thermal energy U is the sum of U(rot), how fast they are spinning, + U(trans) - how fast they are moving in one particular direction, and + U(vib) - where the atoms in the molecule would seem to bounce back and forth in their bonds with respect to the position of other atoms. Increasing the thermal energy would increase the speed of these motions.

The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
