Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction...
When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.

∙ 14y agoIf the object falling is falling at a constant velocity, i.e. terminal velocity, then the upward force of air resistance will be equal to the downward pull of gravity. If not, then the force of air resistance will be less than the pull of gravity, and the object will be accelerating with a force equal to the difference, until terminal velocity is reached

When an object is falling at terminal velocity what is the net force acting on the object?
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.
If a ball is dropped from the top of a building the upward force of air resistance becomes equal to the downward pull of gravity what will happen when the two forces become equal in magnitude?
The ball will fall at a constant speed
How does the force of gravity on a raindrop compare with the air drag it encounters when it falls at a constant velocity?
If the vertical speed is constant, that means there is zero vertical acceleration. If the vertical acceleration is zero, that means the net vertical force on the object is zero. If the net vertical force on the object is zero, that means the downward force (weight) and upward force (air resistance) are equal.
If you were to weigh yourself in an elevator that is in free fall would you weigh more?
Free fall means the upward acceleration of air resistance cancels out the downward acceleration of gravity, leaving only your mass. If you're confused about the difference between mass and weight: Weight = (mass) * (gravity (9.8 m/s^2)) Mass = weight/gravity
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.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
How does the weight of a falling body compare with the air resistance it encounters after it reaches terminal velocity?
If its speed of fall is no longer changing, then its acceleration is zero. That tells you that the forces on it must be balanced, so the upward force of air resistance must be exactly equal to the downward force of gravity.
How can a person jump higher on the moon?
Gravity is what gives us our weight. Weight causes downward resistance to our legs and jumping muscles. This slows down how fast we move, as well as less resistance of upward inertia. On the moon the force of graivity is much less, and thus our muscles have less resistance, and our upward inertia will continue more than if there were more gravity.
How many forces act on a body when a body is thrown upward?
Once it is in the air, the main forces are gravity, and air resistance.
Is the upward force that opposes the force of gravity?
Lift is the upward force that opposes the force of gravity.
Why do falling objects reach a terminal velocity?
When the force of friction due to air resistance at that speed becomes equal to the object's weight. At that point, the sum of the vertical forces on the object is zero, so it no longer accelerates.
What is an upward force?
It is a force which acts in the upward direction.
What force enables a man to walk on the ground?
Gravity,contact force, friction, air resistance
What happens to a falling object when the of air resistance the force of 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.
What is reached when the downward pull of gravity is equal to the upward push of air resistance?
The object would stop falling. This is what allows things to float, and what keeps planes in the air.
What is the greatest velocity a fallingobject reaches?
It's called terminal velocity and it's when the downward force of gravity equals the upward force of drag due to air resistance.
What is the upward force that works against gravity?
Any upward force works against gravity,since they act in opposite directions.
