defall

Defall refers to the act of falling downwards, typically due to gravity. It is a common physical phenomenon experienced by many objects and living beings. In the context of physics, falling is a result of the force of gravity pulling an object towards the center of a celestial body, such as Earth. The speed at which an object falls is influenced by factors like its mass, shape, and the presence of air resistance. For instance, a feather and a stone dropped from the same height will fall at different rates due to air resistance acting on the feather.

In everyday language, "defall" can also be used more broadly to describe a descent or collapse. This could include the falling of leaves from trees in autumn, the crumbling of a structure, or even a metaphorical decline in status or fortune. The term emphasizes the movement from a higher position to a lower one. Understanding the mechanics of falling is crucial in fields such as engineering, where it is important for designing safe structures and understanding projectile motion, and in sports like skydiving, where controlled descent is paramount.
