Universal gravitation

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation states that every object in the universe attracts every other object 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 happens to the gravitational force between two objects if the distance between them is doubled?

Back

The gravitational force is reduced to one-fourth of its original value.

Front

Who is credited with the formulation of the Law of Universal Gravitation?

Back

Sir Isaac Newton.

Front

What is the formula for calculating gravitational force?

Back

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 objects, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

If two objects have masses of 10 kg and 20 kg and are 2 meters apart, what is the gravitational force between them?

Back

F = G * (10 * 20) / (2^2) = 6.674 × 10^-11 * 200 / 4 = 3.34 × 10^-9 N.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects; larger masses result in a stronger gravitational attraction.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases; greater distances result in weaker gravitational attraction.

Front

What is the relationship between gravitational force and the square of the distance?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of 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.
