    Explanation:

    In colder clouds: droplets formed by Bergeron mechanism. But, in many parts of the world the air is too warm for ice crystals to form. This being the case, rain and snow cannot develop following the Bergeron Process. Instead, tiny droplets form as they collide into one another creating larger and larger droplet, this is known as collision-coalescence process. So, warmer clouds are associated with this keyword.

    Fermi was a physicist who came up with the concept of the fermi unit. The word “fermi“ is used in physical science and chemistry to measure extremely small amounts of something.

    In physics, for example, one fermi could be defined as the amount of space an electron would take up if it were traveling at the speed of light, which is about 300 million meters per second. The fermi unit is one ten–millionth of a meter (1E–10 m).

    In nuclear science, the fermi unit is used to measure how big an atomic nucleus is. The word “fermi“ can also be used in chemistry to refer to the amount of space that a hydrogen atom would take up if it were traveling at light speed, which means it would have about one–quarter of a millionth of a centimeter in diameter.

    A “fermi–steradian“ is one ten millionth of the total amount of light energy that falls on an object from all directions (1E–10 sr).

    Potential energy

    Kinetic energy

    If the object is in motion, then it has Kinetic energy (KE). Potential energy (PE) is energy that is “stored” because of the position and/or arrangement of the object.

    Hence, another name for energy of motion is called Kinetic energy.
