Law of Gravitation

Front

What is the Law of Gravitation?

Back

The Law of Gravitation states that every point mass attracts every other point mass in the universe 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.

Front

What is the formula for the Law of Gravitation?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the universal gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

What is the value of the Universal Gravitational constant (G)?

Back

G = 6.673 x 10^-11 Nm^2/kg^2.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What happens to the gravitational force when two objects are moved closer together?

Back

The gravitational force between them increases.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force is directly proportional to the product of the masses of the two objects.

Front

What is an example of gravitational force in everyday life?

Back

The force that keeps us grounded on Earth is an example of gravitational force.

Front

Why do we not feel the gravitational pull of small objects like a pencil?

Back

The gravitational force exerted by small objects is too small to be felt due to their low mass.

Front

What is the effect of gravity on objects in free fall?

Back

Objects in free fall experience acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth.

Front

What is the concept of weight in relation to gravity?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * gravitational acceleration.
