Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.

As an object gains speed, its drag increases. You'll notice it when you run vs. walk. In a case of terminal velocity, the downward force of gravity equals the upward force of drag exerted on the object that is falling. The net force on the body is then zero, and the result is that the velocity of the object remains constant (Newton's first law).

When an object is in free fall, it is accelerating toward the Earth because of the force of gravity (Newton's second law says Force = mass*acceleration, so we know there is acceleration). However, air resistance is a drag force, which is the resistance that air molecules give to the moving object; this force increases as the object's speed increases. Eventually, this air resistance will be high enough when the object is at its terminal velocity that it will be equal in magnitude and opposite in direction to the force of gravity. The net force is therefore zero, so the object does not change speeds. (However, it might as the force of gravity increases slightly as the object falls further, and also as the density of air changes on the way down through the atmosphere.)

Air resistance determines the terminal velocity because at the time where the air resistance overcomes the force of gravity the object can fall no faster. In other words gravity can no longer overcome the force of the air.

When something reaches terminal velocity, the upward force of air resistance exactly balances the downward force of gravity. As a result, the object no longer accelerates. It will continue to fall at the same rate, instead of continually accelerating.

at terminal velocity, force due to air resistance = force due to (mass * gravity)

Then the downward force of gravity and the upward force of air resistance

are equal, and the object's acceleration ceases.

How is gravity related to terminal velocity?

Based on the 9th grade book of Physical Science... Gravity is a force that acts between two masses, and Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. So, gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration... which ties together terminal velocity.


When air resistance equals pull of gravity?

When air resistance equals the pull of gravity, terminal velocity is reached. This is experienced by all falling objects if given enough time, and this is classically explained in Physics using skydivers.


What is velocity at which a falling object travels when the force of air resistance matches exactly the downward force of gravity?

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


How does air resistance affect fallig objects?

terminal velocity is the final maximum velocity of a falling object.


When the only force acting on a falling object is gravity the objects is said to be?

What would happen if terminal velocity did not occur?

When the speed (of falling) is increased, the force of gravitation will be the same, but the air resistance will increase. At some speed, the two will be in balance - there will be no more acceleration, and the object is said to have achieved terminal velocity.


What happens to a falling object when the force of gravity equals to the force of air resistance?

the object will floatit shows increasing acceleration


When gravitational forces and air resistance equalize on an object that is falling toward earth and the objects stop accelerating its velocity is called the?

Is terminal velocity the same speed for any weight?

Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.


What is it called when a falling objects stops accelerating?

it stops accelerating at terminal velocity due to the air


What is the speed at which the acceleration of a falling objects falls to zero because air resistance balances its weight?

This is known as terminal velocity.


How does acceleration affect falling objects?

As objects fall, they are accelerated by the force of gravity, which causes them to continually fall faster, until they either reach the ground, or until they reach what is known as terminal velocity, which is the speed at which air resistance is equal to the force of gravity, so that the falling object does not accelerate any more.
