Newton's universal gravity law

Front

What is Newton's universal law of gravitation?

Back

It 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 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

G = 6.674 × 10^-11 N(m/kg)^2, it is the proportionality constant in Newton's law of universal gravitation.

Front

How does mass affect gravitational force?

Back

Gravitational force is directly proportional to the masses of the objects; as mass increases, gravitational force increases.

Front

How does distance affect gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two masses; as distance increases, gravitational force decreases.

Front

If the distance between two objects is halved, how does the gravitational force change?

Back

The gravitational force increases by a factor of four.

Front

What happens to gravitational force if both masses are doubled?

Back

The gravitational force becomes four times greater.

Front

What is the relationship between gravitational force and weight?

Back

Weight is the force of gravity acting on an object, calculated as W = m * g, where g is the acceleration due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the significance of gravitational force in the universe?

Back

Gravitational force is responsible for the attraction between celestial bodies, governing the motion of planets, stars, and galaxies.
