Here's why:
* Gravity vs. Air Resistance: When an object falls, gravity pulls it downwards. As it falls faster, air resistance (drag) also increases, pushing against the object's motion.
* Balance: Eventually, the force of air resistance equals the force of gravity. At this point, the object stops accelerating and reaches a constant speed, which is its terminal velocity.
* No More Acceleration: Since the forces are balanced, the object doesn't accelerate any further, even though it's still falling.
Important Note: Terminal velocity depends on factors like the object's shape, size, mass, and the density of the air.
