What is Universal Gravitation?

Back

Universal Gravitation is a physical law stating that every mass attracts every other 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 calculating gravitational force?

Back

The formula for gravitational force (F) is F = G * (m1 * m2) / r^2, where G is the gravitational constant (6.674 × 10^-11 N(m/kg)^2), m1 and m2 are the masses of the objects, and r is the distance between their centers.

What happens to gravitational force if the distance between two objects is doubled?

Back

If the distance between two objects is doubled, the gravitational force between them becomes one-fourth of the original force, according to the inverse square law.

What is the gravitational force acting on a 5 kg object on Earth?

Back

The gravitational force (weight) acting on a 5 kg object on Earth is approximately 49 N, calculated using F = m * g, where g is approximately 9.8 m/s².

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is a fundamental physical constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved; the greater the mass, the stronger the gravitational attraction.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases; specifically, it is inversely proportional to the square of the distance.

Front

What is the relationship between gravitational force and mass?

Back

Gravitational force is directly proportional to the product of the masses of two objects; if either mass increases, the gravitational force increases.

Front

What is the significance of the Law of Universal Gravitation?

Back

The Law of Universal Gravitation explains the gravitational attraction between all objects with mass, providing a framework for understanding planetary motion, tides, and other phenomena.

Calculate the gravitational force between two 5 kg objects 0.750 m apart.

Back

The gravitational force is approximately 2.96 × 10^-7 N.
