When there is no air resistance, an object will fall at its terminal velocity, which is the maximum speed it can reach due to gravity alone. In the absence of air resistance, the object will continue to accelerate until it reaches this terminal velocity, experiencing no upward force to oppose its downward motion.

An object in free fall what happens until it reaches terminal velocity?
During free fall, an object accelerates at a constant rate due to gravity. As the object falls, air resistance increases, causing the acceleration to decrease. Eventually, the object reaches terminal velocity, where the air resistance equals the gravitational force, resulting in a constant velocity.
What happens to free-fall velocity when air resistance equals weight?
When air resistance equals weight, the net force on the object becomes zero, resulting in a constant velocity known as the terminal velocity. In the case of free fall, the object will continue to fall at this terminal velocity as long as the forces remain balanced.
What are the factors that affect the speed of an object in free fall with air resistance?
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
What happens when an object is dropped from a helicopter?
When an object is dropped from a helicopter, it will fall due to gravity. Its speed and direction will be influenced by air resistance and any wind present. The object will accelerate until it reaches its terminal velocity, which is the maximum speed at which the air resistance equals the force of gravity.
Is an object in free fall with less air resistance fall with a greater acceleration?
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
Why don't objects fall to earth at the same velocity?
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.

In free fall when the air resistance is equal to the weight of the falling object we say that the object has reached velocity?
In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.

No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
When an object in free fall?
An object is in free fall when only gravity and air resistance (drag) are acting on it. In space, free fall excludes drag.
What is terminal velocity and what causes it?
Terminal velocity is the constant speed that an object reaches when the drag force of the air resistance is equal in magnitude and opposite in direction to the force of gravity acting on the object. This balance of forces causes the object to stop accelerating and fall at a constant speed.
How long will it take an object to fall 60000 feet?
It would take approximately 50 seconds for an object to fall 60,000 feet in a vacuum without air resistance. However, in reality, factors like air resistance would affect the actual time it takes for the object to fall.
What force slows down a falling object?
Gravity is the force that causes objects to fall, while air resistance or drag slows down a falling object as it moves through the air. The larger the surface area of the object, the greater the air resistance force, which opposes the force of gravity and slows the object down.
How can one calculate air resistance in free fall?
To calculate air resistance in free fall, one can use the formula for air resistance force, which is given by F 0.5 Cd A v2, where Cd is the drag coefficient, A is the cross-sectional area of the object, is the air density, and v is the velocity of the object. By plugging in the values for these variables, one can determine the air resistance acting on an object in free fall.
