The air friction is proportional to surface area and square of velocity and so it increase square as velocity increase. At the rate when these friction force is balance with gravity force, there is no future acceleration and so it reach terminal velocity.

They don't hit the ground with constant velocity because of wind, size, interference, and so on.

What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?

If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.


An object is falling at its what if it falls at a constant velocity?

rate of acceleration


What would you call it when air resistance the force of gravity and a falling object stops accelerating?

When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.


What is meant by terminal velocity of a falling object?

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.


Is it possible for the sky diver in this picture to be falling at a constant velocity?

Any skydiver can fall at a constant velocity. This is called the, "Terminal velocity". Since we do not have the picture that you mention, nothing more can be assumed.


What is the net force on a falling object when it reaches terminal velocity?

An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.

Why doesn't a raindrop accelerate as it approaches the ground?

A falling snowflake or raindrop does not accelerate as it approaches the ground because their mass doesn't change. The form is not affected throughout the fall so it is already approaching the ground at terminal velocity. Hope this helps.


What is the greates velocity a falling object can reach called?

The fastest velocity a falling object can reach is called its terminal velocity. This happens when the force of air resistance is equal to the downwards force of weight (gravity), so the object is in equilibrium, and thus reaches a constant velocity.


When air resistance balances the weight of an object that is falling the velocity remains blank?

Constant


Is it possible for an object to have a constant acceleration and a non-zero velocity?

Yes, a falling apple meets that condition.


Explain the effect that gravity has on the velocity of falling objects?

The force of gravity causes the falling object's velocity to grow in magnitude by 9.8 meters per second every second, while its direction remains constant.
