What happpens to velocity as a drop distance increases relate this to the concept of terminal velocity?

A falling body initially falls at a rate of -9.8m/s2, the acceleration due to gravity. Because of the drag force of the air, which is an upward force that opposes the force of gravity, the body's acceleration will decrease as it continues falling. When the drag force equals the weight of the falling body, there will be no further acceleration, and the body will have reached terminal velocity.

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 is velocity at which a falling object travels when the force of air resistance matches exactly the downward force of gravity?
newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity
What happens to an object in free fall as it reaches terminal velocity?
every second the velocity increases by 9.8m/s per second per second
How does the length of an object change as its velocity increases?
As per Einstein's theory of relativity as velocity of the rod increases then its length would be shortened by a factor ./ 1 - (v/c)^2 where v is the velocity of the rod and c the velocity of light. This is known as Lorentz Fitzerald contraction.
What does a parachute do to terminal velocity?
It decreases the terminal velocity of the parachutist.
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.
When an object reaches terminal velocity and there is no net force what is the initial force that got it going to keep it in motion?
Gravity. The object starts at zero velocity, and gravity always pulls the same. Drag, however, increases when velocity increases. Terminal velocity is when gravity has accelerated the object to the speed where drag is the same as gravity.
How does the total distance changes as the total time increases in case of uniformly motio?
For uniform motion, distance = velocity*time where uniform implies that the velocity is a constant. Therefore distance = v*time and so, if time increases by t, the distance increases by vt.
When a mechanic increases the force acting on an object what happens to the distance the object moves?
When the Force increases on an Object, the Distance it travels INCREASES, as does its Velocity.

Distance equals velocity time the equation sHow is that distance varies as time?
Distance is dependent on time. If there is no time, there is no distance, as distance = velocity * time. As time or speed increases so will distance, therefore, if distance increases, either speed or time must increase. If either speed or time = 0, then distance will equal 0.
What does a parachute do to terminal velocity?
It decreases the terminal velocity of the parachutist.
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
How does the weight of a falling body compare with the air resistance it encounters before it reaches terminal velocity?
The weight exceeds the force of air resistance, but as the speed increases the air resistance increases, so the net force (weight - air resistance) falls. When the difference becomes zero the acceleration ceases and you have terminal velocity.
What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
