Why acceleration due to gravity is not same everywhere?

Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.

Which law of motion explains why the force of gravity between two objects is the same for each object regardless of their mass?

Newton’s second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.

How does Newton’s law of universal gravitation relate to law of interaction?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

In what sense is gravity an inverse square law?

The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object’s centers. Altering the separation distance (d) results in an alteration in the force of gravity acting between the objects.

How does the acceleration of gravity vary on Earth?

The acceleration g varies by about 1/2 of 1 percent with position on Earth’s surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.

Why does acceleration due to gravity varies on the earth surface?

As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.

Do all objects experience the same force of gravity?

On earth, all objects (whether an elephant or a feather) have the same force of gravity. The elephant weighs more than the feather, yet they each have the same mass.

Why 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.

What do you mean by acceleration due to gravity?

When an object falls freely towards the surface of earth from a certain height, then its velocity changes and this change in velocity produces acceleration in the object which is known as acceleration due to gravity denoted by g. The value of acceleration due to gravity is. g=9. 8m/s2.

Which of the following has symmetry a acceleration due to gravity B law of gravitation?

Acceleration due to gravity varies from place to place. So it has no symmetry Law of gravitation has symmetry, because it does not depend on any physical quantity.

What is acceleration due to gravity in physics?

When a body is fallen towards the earth it experiences a change in its acceleration due to the earth’s gravitational force. This acceleration is called acceleration due to gravity. This is the acceleration that is attained by an object due to the gravitational force. The SI unit of acceleration due to gravity (g) is m/s².

What happens to acceleration when a body falls to Earth?

When a body is fallen towards the earth it experiences a change in its acceleration due to the earth’s gravitational force. This acceleration is called acceleration due to gravity. This is the acceleration that is attained by an object due to the gravitational force.

What happens to gravity as you move away from the Earth?

Altitude: When a body moves away from the surface of the earth the force of attraction decreases as the distance between the earth and the body increases. Depth: When a body is put inside the earth’s surface the acceleration due to gravity becomes less.

What is the force of gravitation at the equator?

While the force of gravitation is minimum at the equator of the earth approximately 9.78 m/s 2 as the radius of the earth is maximum at the equator Altitude: When a body moves away from the surface of the earth the force of attraction decreases as the distance between the earth and the body increases.
