What is gravitation?

Gravitation is the force of attraction between any two objects with mass.

Who discovered the universal law of gravitation?

Sir Isaac Newton

What does the law of gravitation state?

The law of gravitation states that every particle of matter attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

What is the unit of force of gravitation?

The unit of force of gravitation is Newton (N).

What is the value of the acceleration due to gravity on Earth?

The value of the acceleration due to gravity on Earth is approximately 9.8 m/s^2.

What is the formula to calculate the force of gravitation between two objects?

The formula to calculate the force of gravitation between two objects is F = (G * m1 * m2) / r^2, where F is the force of gravitation, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.

What is the gravitational constant?

The gravitational constant (G) is a fundamental constant in physics that approximates the strength of the gravitational force. Its value is approximately 6.67430 x 10^-11 N(m/kg)^2.

Does the force of gravitation depend on the nature of the objects?

No, the force of gravitation does not depend on the nature of the objects. It only depends on their masses and the distance between them.

What is the difference between mass and weight?

Mass is a measure of the amount of matter in an object, while weight is the measure of the force of gravity acting on an object's mass.

Why do objects fall towards the ground?

Objects fall towards the ground due to the gravitational force exerted by Earth.

Can gravitation act between non-touching objects?

Yes, gravitation can act between non-touching objects. It has an infinite range.

What is the significance of the inverse square law in the law of gravitation?

The inverse square law in the law of gravitation explains how the force of gravity weakens as the distance between objects increases. It states that the force of gravity is inversely proportional to the square of the distance between the centers of the objects.

Does the force of gravity change with altitude?

Yes, the force of gravity decreases with increasing altitude. However, the difference is negligible at small heights compared to the radius of the Earth.

What is the relationship between mass and gravitational force?

The gravitational force between two objects is directly proportional to the product of their masses. As the masses increase, the gravitational force also increases.

How does the force of gravitation affect orbits?

The force of gravitation is responsible for keeping celestial objects in orbit around each other. It provides the necessary centripetal force to maintain the circular or elliptical motion.
