**Thermal Energy:**
Thermal energy is the total energy of all the particles in a substance due to their random motion. It is a form of energy that is associated with the temperature of an object. Thermal energy depends on the number of particles in the substance, their speed (which is related to temperature), and the nature of the substance itself. In general, as the temperature of a substance increases, the thermal energy of its particles also increases, leading to a greater overall energy state.
**Kinetic Energy:**
Kinetic energy is the energy an object possesses due to its motion. It is dependent on the mass of the object and the square of its velocity, and is mathematically expressed by the formula:
\[
KE = \frac{1}{2} mv^2
\]
where \( KE \) is the kinetic energy, \( m \) is the mass of the object, and \( v \) is its velocity. Kinetic energy is associated not just with macroscopic objects (like cars and balls) but also at the microscopic level, where molecules and atoms move and vibrate.
**Temperature:**
Temperature is a measure of the average kinetic energy of the particles in a substance. It indicates how hot or cold an object is and is a critical concept in thermodynamics. Temperature is typically measured using scales such as Celsius (°C), Fahrenheit (°F), or Kelvin (K). A higher temperature means that, on average, the particles in a substance have higher kinetic energy, while a lower temperature indicates lower average kinetic energy. Temperature is not the same as thermal energy, as it does not account for the total energy of all particles but rather the average energy per particle.

**Thermal energy** is the total energy from the motion of all the particles in a substance and is related to its temperature. **Kinetic energy** is the energy that an object has due to its movement, and **temperature** measures how hot or cold something is based on the average speed of its particles.
