What forces have to be balanced for terminal velocity to be reached by an object?

For an object in freefall, terminal velocity is reached when the drag force becomes equal and opposite to the force of gravity. This creates a net force of 0, resulting in no further acceleration.

The blank is reached when the force of gravity is balanced by air resistance the size of the air resistance force depends on the shape of an object and it's speed?
yes force down in newtons = (mass * acceleration due to gravity) constant force up in newtons = ( velocity^2 * drag coefficient) increases with velocity until terminal velocity reached, forces balance , no further acceleration. if mass(m) and terminal velocity(tv) are known, drag coefficient(dc) can be calculated. if : (m * g) = (tv^2 * dc) so: dc = (m * g )/( tv^2) drag coefficient is dependent on shape and texture, and is exclusive to each object. air resistance to motion increases as to the square of velocity
When the forces of an object are blank there is no change in object's velocity?
balanced
Why are the forces balanced on an object falling at terminal velocity?
In a vaccum, different objects have no terminal velocity... the further they fall, the faster they go. So, "air drag" is what provides differing terminal velocities, and the object's shape and weight distribution controls that drag.
What type of change can the balanced forces bring about in an object?
Balanced forces do not bring about any change in motion. If forces are balanced, an object is either at rest, or moving in a straight line at constant velocity.
How much upwards air resistance force is present on a bag that weighs 50 N when it has reached a terminal velocity?
"Terminal velocity" means that it no longer accelerates; forces are in balance. This is only possible if the upward force is also 50 N. (The "50 N weight" represents the downward force of gravity.)
Why is terminal velocity an example of balanced forces?
When terminal velocity is reached, the gravitational force is balanced with the force of resistance.
How does terminal velocity involve balanced forces?
Terminal velocity is an example of balanced forced because the gravitational forces and the air resistance balance each other.
When an object is falling is it balanced or unbalanced forces.?
Not balanced UNTIL it reaches terminal velocity.
What if a falling object reaches this when forces of gravity and air resistance are balanced?
terminal velocity
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.
A falling object is encountering air resistance At the moment the object reaches its terminal speed?
... I think you want to know about forces. At terminal velocity, the force of gravity is balanced by the air resistance, so no further acceleration occurs (balanced forces are the equivalent of an absence of force), which is why we call it *terminal* ("end value") velocity.
Are Terminal velocities balanced or unbalanced?
"Balanced" refers to forces, not to velocities or speeds. If an object is at terminal SPEED, the FORCES on it are balanced.
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
Does A free falling object experiences a balance of forces?
Yes, if it reaches terminal velocity, which is a constant velocity. When terminal velocity is reached, the downward gravitational force is equal to the upward force of air resistance, and the object no longer accelerates.
Why does the shape of the free fall curve tell you about how an object moces when it is in free fall?
if its a velocity / time curve, it will show diminishing acceleration (slope of the curve) up to terminal velocity (forces balanced)
What do you get when you subtract the forces of air resistance from the forces of gravity?
Terminal Velocity
Can all forces of a car be balanced if it is moving a constant velocity?
That's exactly what we must conclude. If the forces on the car were not balanced, then its velocity would have to change.
