Here's why:
* Gravity: Pulls the object downwards, constantly accelerating it.
* Air Resistance: Acts opposite to the direction of motion, increasing with speed.
As an object falls, it accelerates due to gravity. This increases its speed, which in turn increases air resistance. At a certain point, the force of air resistance becomes equal in magnitude to the force of gravity. At this point, the object stops accelerating and reaches a constant speed. This constant speed is called terminal velocity.
Factors affecting terminal velocity:
* Mass of the object: A heavier object has a greater gravitational force acting on it, leading to a higher terminal velocity.
* Shape and surface area of the object: A larger surface area means more air resistance, resulting in a lower terminal velocity.
* Density of the air: Denser air provides more resistance, leading to a lower terminal velocity.
