When a falling object has reached its teminal velocity its accleration?
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
An object is falling at its what if it falls at a constant velocity?
If an object is falling at a constant velocity, then the net force acting on it is zero. This means that the force of gravity pulling the object downward is balanced by an equal and opposite force. The object will continue to fall at a steady speed without accelerating.
What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
When the upward and downward forces on a falling object are equal the object reaches?
When the upward and downward forces on a falling object are equal, the object reaches terminal velocity. At terminal velocity, the object stops accelerating and falls at a constant speed.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
Can an object have velocity and acceleration vectors that point in opposite directions?
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
What forces are acting on an object when it is falling at terminal velocity?
When an object is falling at terminal velocity, the forces of gravity pulling it downward and air resistance pushing upward are balanced. This results in a constant velocity for the object as it falls.
What happens to the acceleration and velocity when an object in free fall moves downward?
In free fall, the acceleration of the object remains constant at 9.8 m/s^2 directed downward towards the center of the Earth. The object's velocity will increase as it falls due to the constant acceleration, until it reaches terminal velocity if air resistance is present.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What is the greatest velocity a fallingobject reaches?
The greatest velocity a falling object reaches is called terminal velocity. It occurs when the force of gravity pulling the object downward is balanced by the force of air resistance pushing upward. At terminal velocity, the object falls at a constant speed with no further acceleration.
What is downward velocity?
Downward velocity refers to the speed at which an object is falling towards the ground or moving in a downward direction. It is commonly measured in units such as meters per second or feet per second. A positive downward velocity indicates the object is accelerating downward, while a negative velocity means the object is moving upward.
