The terminal velocity of a falling object is the constant speed where the force of gravity is equal to the force of drag. Then the forces cancel each other out.
Essentially, terminal velocity is when the speed of a falling object is no longer changing. It isn't accelerating or slowing. It's constant.

Terminal velocity of a falling object is the constant speed at which the object no longer accelerates due to air resistance. At this point, the gravitational force pulling the object downwards is equal to the force of air resistance pushing against it, resulting in a net force of zero. This causes the object to fall at a constant speed.
The velocity of an object includes both its speed (magnitude of the velocity) and its direction of motion. It is a vector quantity that describes how fast and in which direction an object is moving. Velocity can be constant or changing depending on any accelerations acting on the object.
Acceleration refers to the rate at which an object's velocity changes over time. It can be an increase or decrease in speed, or a change in direction. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
I'm not sure if you meant "momentum" instead of "momentom." Momentum is a physics concept that describes the quantity of motion an object has, determined by its mass and velocity. It reflects how difficult it is to stop an object when it is in motion.
An acceleration of -2 m/s^2 means that the velocity of an object is decreasing by 2 meters per second every second. The negative sign indicates that the acceleration is in the opposite direction of the velocity.
Centripetal acceleration is the acceleration directed towards the center of the circular path of an object in motion. When centripetal acceleration is perpendicular to velocity, it means that the acceleration is acting in a direction that is perpendicular to the direction of the object's motion at any given point along the circular path.
