An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.
Objects are said to have reached their terminal velocity when they no longer accelerate.
it depends on the mass of the object
Perhaps you mean terminal velocity. This is the maximum velocity reached by an object falling to the ground when the acceleration due to gravity is matched by the drag resistance of the air through which it is falling.
final velocity, or terminal velocity.
It's terminal velocity.
Terminal velocity is reached when the force of gravity is equal to the drag (force) on an object.
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.
Terminal velocity is the velocity at which a falling body reaches constant velocity due to air resistance.
If you are talking about free fall, acceleration due to gravity and velocity will both be negative, until terminal velocity is reached, at which point the falling object is no longer accelerating and has constant negative velocity.
Since the direction of the motion remains constant throughout the free fall, once the speed also becomes constant, the acceleration is zero.
When the velocity stops changing, then, by definition, the acceleration is zero.
In that case, it is said to have achieved terminal velocity.
"Terminal Velocity". Usually about 125 mph.
neither speed nor acceleration
it stops accelerating at terminal velocity due to the air
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.
reached "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.
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.
It's called terminal velocity! :)
Terminal velocity is the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity. An object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the air, water, or other fluid through which it is moving.
Take an accelerometer with you when you jump, and at the point that it reads, "zero", the terminal velocity has been reached.
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.
1) Terminal velocity is never quite reached; a falling object will get closer and closer to terminal velocity. You can put some arbitrary limit, for which you can say that "for all intents and purposes, terminal velocity has been reached", for example, 95%, or 99%, of terminal velocity. 2) The actual terminal velocity varies for different objects. A feather will approach its terminal velocity almost instantly; a heavy object, without much surface area (for example, a steel ball) will have to fall more seconds (and more meters or feet), before it is anywhere close its terminal velocity.
