# When there is no air resistance objects fall at constant?

## When there is no air resistance objects fall at constant?

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

## What happens when an object falls freely without air resistance?

If air resistance and friction are negligible, then in a given location (because gravity changes with location), all objects fall toward the center of Earth with the same constant acceleration, independent of their mass, that constant acceleration is gravity.

What is the constant of a falling object?

The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth. The weight, size, and shape of the object are not a factor in describing a free fall.

### Why do objects fall at the same rate without air resistance?

Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

### What feature of an object does not affect air resistance?

Air resistance, on the other hand, does not depend on mass, only on the density of air, the shape of the object, and the velocity of the object (or the square of the velocity, depending on the size and density– air resistance is messy…).

What happens when an object falls freely?

When an object falls freely, its potential energy gets converted into kinetic energy. When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.

## How do objects fall at the same rate?

The gravitational acceleration g decreases with the square of the distance from the center of the earth. So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner.

## What is the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity?

When drag is equal to weight, there is no net external force on the object, and the acceleration becomes zero. The object then falls at a constant velocity as described by Newton’s first law of motion. The constant velocity is called the terminal velocity.

Is air resistance a constant force?

Air resistance is a force that depends on the velocity. This means that the force (and thus the acceleration) is not constant. During this short time interval, the forces are roughly constant.

### What forces act horizontally in the absence of air resistance?

In the absence of air resistance there are no forces or components of forces that act horizontally. A velocity vector can only change if there is acceleration (acceleration is the rate of change of velocity).

### Why does velocity remain constant in the absence of air resistance?

When In the absence of air resistance, why does the horizontal component of velocity for a projectile remain constant while the vertical component of free fall? In the absence of air resistance there are no forces or components of forces that act horizontally.

What is the acceleration of the ball when it is caught?

Its acceleration is A ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would be Suppose an object is in free fall. Each second the object falls

## How do you accelerate a projectile without air resistance?

In order to accelerate a resultant force is required (according to Newton’s Second Law, → F = m→ a ). In the absence of air resistance the only force acting on a projectile in flight is the weight of the object. Weight by definition acts vertically downwards, hence no horizontal component.
