What is gravitation?

Gravitation is the force of attraction between objects with mass.

Who discovered the law of universal gravitation?

Sir Isaac Newton

What is the formula to calculate gravitational force?

The formula is F = G * (m1 * m2) / r^2, where F is the gravitational force, 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 value of the gravitational constant?

The value of the gravitational constant is approximately 6.67430 × 10^-11 N(m/kg)^2.

What is the unit of gravitational force?

The unit of gravitational force is Newton (N).

What are the factors affecting gravitational force?

The factors affecting gravitational force are the masses of the objects and the distance between them.

What is the law of universal gravitation?

The law of universal gravitation states that every particle in the universe 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 them.

How does gravitation affect the motion of objects?

Gravitation causes objects to accelerate towards each other, affecting their motion.

What is the difference between mass and weight?

Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

What is free fall?

Free fall is the motion of an object under the influence of gravity only, without any other forces acting on it.

What is gravitational potential energy?

Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field.

What is escape velocity?

Escape velocity is the minimum velocity an object needs to escape the gravitational pull of a planet or other celestial body.

What is centripetal force?

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

What is the acceleration due to gravity on Earth?

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

What is the difference between gravitational field and gravitational force?

Gravitational field is a region in which an object experiences a gravitational force, while gravitational force is the actual force of attraction between objects.
