Air resistance is directly proportional to velocity. If you think about it, the faster an object is moving, the more frequently and harder said object will collide with the molecules in the air. It's these collisions that create air resistance.
Just in case you have problems visualizing, let's imagine knocking a nail with a hammer, into the wall.
When you knock the nail, slowly, the force exerted is too gentle to get the nail into the wall.
On the other hand, when you knock the nail, fast, the force exerted is just right to get the nail into the wall.
For explanations using formulas, let's use Newton's 2nd law:
Force(Resultant)= Mass x Acceleration
The nail's mass is a constant.
If you use a greater force, working out the formula, acceleration increases.
Or, rather, if you accelerate the motion of the nail into the wall (which means you have to accelerate first), the force you exert automatically becomes greater.
So, now, you can read back the first paragraph and make sense out of it.

(In actual fact, it usually letting the air get back to where it belongs that takes the most energy ... and it's referred to as turbulence.)

How is terminal velocity reached by a falling object?
While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

How does a parachute reduce the terminal velocity of a person falling through the air?
The parachute increase the surface area and so therefore increase air resistance, slowing the person down, and reducing terminal velocity.
How does air resistance affect terminal velocity?
Without air resistance, there would be no such thing as terminal velocity.
If air resistance is negligible then terminal velocity is the velocity of shock waves?
If resistance is negligible, then there is no terminal velocity.
When a object falls what does it reach because of air resistance?
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.

When an object falls through the air and encounters air resistance its overall speed will be?
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
Do the velocity of falling objects does not change?
If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
Air resistance increases and terminal velocity decreases when the parachute has opened.
What affects air resistance?
Fluid density, relative velocity, and object shape affect air resistance.
Why a raindrop falling vertically through still air reaches a constant velocity?
The air resistance will increase to the point where it counters the downward acceleration.
Air resistance depends on?
The velocity of a moving object....
When an object falls through the air encounters air resistance its overall speed will be than if it had not encountered air resistance?
The resistance do obstruct the object. The object always travel slower with air resistance. Air resistance is higher with velocity and the object falling through air would have a limited velocity that it can't go through.
