Universal Law of gravitation

Front

What is the Universal Law of Gravitation?

Back

The Universal 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.

How does distance affect gravitational force?

Back

The gravitational force decreases as the distance between two objects increases. Specifically, if the distance is tripled, the gravitational force becomes one-ninth of its original value.

What happens to your mass if Earth's mass is halved?

Back

Your mass remains unchanged because mass is not affected by gravitational force.

What is the Gravitational Constant (G)?

Back

The Gravitational Constant (G) is a fundamental physical constant used in the calculation of gravitational force between two bodies. Its value is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

What is Coulomb's Constant (k)?

Back

Coulomb's Constant (k) is a proportionality constant in Coulomb's law, which describes the electrostatic force between charged objects. Its value is approximately 8.99 × 10^9 N(m^2/C^2).

Front

How do gravitational and electrostatic forces compare?

Back

Coulomb's constant (k) is much larger than the gravitational constant (G), indicating that electrostatic forces are significantly stronger than gravitational forces at the atomic level.

Front

What is the formula for gravitational force?

Back

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

Front

If two objects have masses of 8000 kg and 1500 kg and are 1.5 m apart, what is the gravitational attraction between them?

Back

The gravitational attraction is approximately 3.6 × 10^-4 N.

Front

True or False: Gravity attracts all objects towards one another.

Back

True.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * gravitational acceleration (W = mg). Mass is a measure of the amount of matter in an object and does not change with location.
