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 a falling when object when the force of air resistance equals the force of gravity?
Terminal velocity (steady speed).
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.
What happens to a falling objects velocity as the object falls?
If air resistance can be neglected, the object will fall faster and faster. If air resistance is significant, the object will fall faster and faster, until it asymtotically approaches a "terminal velocity" - the velocity at which the downward pull of gravity is in equilibrium with the air resistance.
What is terminal velocity and what causes it?
Terminal velocity is an object's maximum speed while falling through the air, and it happens when the force created by air resistance is equal to the force of gravity.
What happens to the object when it has balances forces acting on it?
Such an object will not accelerate - its velocity won't change.
The largest velocity reached by a falling object is its what?
Its terminal velocity. This happens when the net force on the object is zero and therefore it stops accelerating. This makes sense intuitively because the faster something falls, the more air resistance it experiences. Once this air resistance force reaches the force of weight of the object, terminal velocity has been reached.
What happens when the drag force of air resistance is equal to the force of gravity on an object as it is falling?
This state is known as terminal velocity. In it's current shape, an object as described cannot travel any faster. The force of gravity is constant where as the force of air resistance increases with velocity so it takes time for an object to reach its terminal velocity.
What happens to free-fall velocity when air resistance equals weight?
If air resistance equals the force of gravity, the object will cease to accelerate, so its velocity will remain constant.
When the speed an object reaches the force of gravity is balanced by the force of air resistance called inertia?
No, terminal velocity is the speed at which an object comes to a resting point in acceleration. This happens when the effect of gravity on said object becomes balanced with the air resistance.Dictionary definition: the velocity at which a falling body moves through a medium, as air, when the force of resistance of the medium is equal in magnitude and opposite in direction to the force of gravity.
What happens to the speed of an object that is falling in free fall?
It increases at the rate of acceleration due to gravity, 9.8m/s2, until air resistance and the weight of the object become equal but opposite in direction. At that point there is no further acceleration and the object has reached its maximum velocity, called terminal velocity.
What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
Explaine what happens to the velocity and the acceleration of an object in fall?
Neglecting any effects of air resistance . . . -- velocity increases continuously, at a constant rate -- acceleration is constant
When an object is falling its motion is most affected by air resistancce when?
The faster it falls, the more it is affected by air resistance, since air resistance increases with speed. What usually happens in practice is that the object falls faster and faster, and eventually approaches the "terminal velocity" - a speed at which the force of gravity and the force of friction are in balance.
What happens to speed of an object as it is falling?
The speed of an object as it falls will increase up to a point at which it reaches its terminal velocity. This occurs because there are two forces acting on the object, the force of gravity and the force of air resistance. The force of gravity is equal to the objects mass times the acceleration due to gravity. The force of air resistance can be estimated as a constant(b) times the object's velocity. When the velocity is high enough, the object's upward force due to air resistance is equal to the force of gravity and therefore the object will no longer speed up. Hope that helps
What happens when you open a parachute?
As the parachute opens, it moves against air which causes air resistance. The air resistance is like friction and will slow down the falling person.
What happens to a falling object when the force of air resistance equals the force of gravity?
the object will floatit shows increasing acceleration
What happens when the force of air resistance is equal to the downward force of gravity?
This is called Terminal Velocity. Gravity pulling downwards matches the air resistance pushing upwards to cancel the acceleration out. Many people misunderstand this and believe that this means that the object falling is no longer moving, but it is speaking in terms of acceleration, not speed. So the acceleration from before terminal velocity was reached will still be in affect, but the object will be neither gaining or losing speed.
How is terminal velocity reached?
An object falls faster and faster, until the force of the air resistance equals the force of gravity. When that happens, the object will not accelerate (speed up) any more, and is said to have reached terminal velocity.
What happens when the force of air resistance equal the force of gravity?
Then acceleration becomes zero, and the object continues falling at a constant speed.
What is the net force if an object is skydiving?
If an object does not change position: spin, rotate the net force is zero. When it happens an object is falling with terminal velocity.
What happens to air resistance as the speed of a falling object increases?
Air resistance will increase as the speed of a falling object increases.That is the usual scenario. However air density is also a factor. If a skydiver was falling and encountered an area of lower air pressure due to atmospheric conditions, then any increase of speed would be due to a lower air resistance.I have fallen through air layers where there has been a noticeable increase in air temperature and therefore a drop in air density.Because of all the variables at play, it would be difficult to prove or disprove that air resistance could actually lower and cause a body ( skydiver ) to accelerate.This would only happen after the initial attainment of terminal velocity.
What happens when the forces upthrust and air resistance are applied to objects?
If enough upthrust is added to an object then it will be pushed upwards. If enough air resistance is applied to an object then it will move in the direction which the air resistance is pushing it in. If you are already falling, then you will have air resistance. If it is increased when you open a parachute for instance, then you will slow down.
What happens to a falling object when the force of air resistance equals gravity?
Falling objects increase their speed as they fall, because their weight (the force of gravity) pulls them to Earth. ... Objects fall faster until they reach their terminal speed, which is reached when the upward (air resistance) and downward (weight)forcesare equal.
