Here's why:
* Gravity: Gravity pulls the object downwards, accelerating it.
* Air Resistance: As the object falls faster, the air resistance (drag) acting against it increases.
* Equilibrium: At terminal velocity, the force of air resistance becomes equal and opposite to the force of gravity. This means the net force on the object is zero.
Key points about terminal velocity:
* Constant Velocity: Once terminal velocity is reached, the object stops accelerating and falls at a constant speed.
* Factors affecting Terminal Velocity: Terminal velocity is influenced by factors like:
* Mass of the object: Heavier objects have a higher terminal velocity.
* Shape and Surface Area: Objects with larger surface areas experience more air resistance, leading to a lower terminal velocity.
* Density of the air: Thicker air creates more resistance.
* Not a Fixed Value: Terminal velocity is not a fixed number. It changes depending on the factors mentioned above.
