The parachutist and the snowflakes do not fall with a constantly accelerating motion because the velocity changes.
Snowflakes and snow crystals are both formed from frozen water vapor, but they have different structures. Snowflakes are clusters of snow crystals that stick together as they fall from the sky. Snow crystals are individual ice crystals that form in the atmosphere. Snowflakes can have a variety of shapes and sizes, while snow crystals typically have a hexagonal shape.
No, you are not accelerating if you are traveling in a constant direction with a constant speed. Acceleration is the rate of change of velocity, so if your velocity remains constant, there is no acceleration.
This discrepancy is known as the "accelerating expansion of the universe." In our model, we incorporate dark energy to explain this acceleration. Dark energy is a hypothetical form of energy that exerts a negative pressure, causing the expansion of the universe to accelerate. By including dark energy in our model, we can account for the observed accelerating expansion of the universe.
Energy is difficult to explain because it is a fundamental concept that manifests in various forms and is not directly observable. It is also constantly changing and transferring between different forms, making it complex to describe in a simple way. Additionally, energy is interconnected with many other aspects of physics, further adding to its complexity in explanation.
Black energy is a theoretical form of energy that has been proposed to explain the accelerating expansion of the universe. It is thought to make up about 68% of the universe and is associated with the concept of dark energy, which remains one of the biggest mysteries in cosmology.
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.

Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
I feel your struggle. The answer is what ever you want it to be.
You explain this: "When the clouds get really cold, stuff drops from them. That stuff is snow."
False question. Electrical energy may be stored in a battery, thus not needing "to be generated constantly." Reask your question with different parameters.

Forces (plural) are balanced if their vector sum is zero. Since an unbalanced force causes an acceleration, if an object isn't accelerating then the forces on it are balanced.
