If he's moving with constant velocity, then the net force on him is zero.
The force of gravity must be exactly balanced by the force of kinetic friction
between him and the air.
The net force itself is the vector sum of gravity and air resistance. If there is
no wind, then the direction of the net force is straight down, toward the center
of the Earth.
The direction is downwards, since that's where gravity pulls.
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.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
An object falling from a tall building would accelerate at a rate of 9.807 m/s2 until it reached terminal velocity, at which point it would not accelerate until it impacted the ground. Its velocity would increase as it fell until reaching terminal velocity, and then 0 when it hit the ground.
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.

the greatest velocity a falling object reaches is terminal velocity
the greatest velocity a falling object reaches is terminal velocity
Its the air resistance that causes the free falling body to reach its terminal velocity
Terminal velocity.

That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.
Yes, but only in free-fall. If I'm driving at 60 mph, I have a constant velocity, but it's not my "terminal velocity" in the sense that there is no limit to my acceleration caused by air friction. But yes, an object in free-fall reaches its terminal velocity when its velocity stops increasing (acceleration=0).
The greatest velocity a falling object reaches is called the terminal velocity.For an object falling at the terminal velocity, the weight force of the objectis balanced by the drag force and buoyant force on the object.W + FDRAG + FBUOYANT = FNET = 0.0
