Here's why:
* Terminal velocity is the constant speed that a freely falling object eventually reaches when the force of air resistance equals the force of gravity.
* Force of gravity pulls the object downwards.
* Air resistance acts in the opposite direction, slowing the object down.
When terminal velocity is reached, the upward force of air resistance perfectly balances the downward force of gravity. Since the forces are equal and opposite, they cancel each other out, resulting in a net force of zero.
This means that the object continues falling at a constant speed (terminal velocity) without accelerating.
