# Why do some objects fall through the air at a different rate?

## Why do some objects fall through the air at a different rate?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together.

### Is the acceleration due to gravity the same for all falling objects when there is no air resistance?

It is also true that a free falling (no air resistance) object falls with an acceleration of 9.8 m/s2—but it’s still just the gravitational field. It doesn’t matter what object you put near the surface of the Earth, the gravitational field due to the Earth is constant and pointing towards the center of the Earth.

When gravity is the only force all objects have the same acceleration?

A simple rule to bear in mind is that all objects (regardless of their mass) experience the same acceleration when in a state of free fall. When the only force is gravity, the acceleration is the same value for all objects. On Earth, this acceleration value is 9.8 m/s/s.

Is acceleration the same in free fall?

An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton’s second law of motion. 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.

## Why does gravity accelerate?

Gravity is a force that pulls objects down toward the ground. When objects fall to the ground, gravity causes them to accelerate. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

### What is the acceleration due to gravity of all objects?

Summary. At any given location on the Earth and in the absence of air resistance, all objects fall with the same uniform acceleration. We call this acceleration the acceleration due to gravity on the Earth and we give it the symbol g. The value of g is 9.81 m/s2.

What is acceleration of free fall due to gravity?

It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

Why does an object accelerate during free fall?

Free Fall is the term that describes the acceleration of objects toward the Earth when dropped at rest. The acceleration of the falling object is due to the force of gravity between the object and the earth.

## Does gravity affect all objects the same?

Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. The mass of an object ALWAYS stays the same. Your mass on Earth will be the same if you were on the moon.

### Do all objects fall at the same acceleration?

the value of g is 9.8 meters per square second on the surface of the earth. 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.

Why do all free-falling objects have the same acceleration?

Is gravity and acceleration the same?

Gravity is a force that pulls objects down toward the ground. When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion.

## What is the acceleration of an object in free fall?

An object in free fall experiences constant acceleration if air resistance is negligible. On Earth, all free-falling objects have an acceleration g due to gravity, which averages

### Does acceleration due to gravity depend on mass of object?

Acceleration due to gravity does not depend upon mass of object If we remove air and then make both paper and stone fall, both will fall with same acceleration of 9.8 m /s 2 it is because of air resistance that stone falls faster but paper takes time to fall Acceleration due to gravity is different at poles and at equator

Do all objects with the same size fall at the same rate?

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. Knowing the acceleration, we can determine the velocity and location of any free falling object at any time.

Why does the Earth’s gravity make things fall so slow?

This is a general characteristic of gravity not unique to Earth, as astronaut David R. Scott demonstrated in 1971 on the Moon, where the acceleration from gravity is only 1.67 m/s2 and there is no atmosphere. In the real world, air resistance can cause a lighter object to fall slower than a heavier object of the same size.
