4-3 Newton's Universal Law of Gravity

Front

What does Newton's Universal Law of Gravity state?

Back

Every object in the universe attracts every other object.

Front

What is the value of the Universal Gravitational constant?

Back

6.67 x 10^-11 N*m^2/kg^2

Front

How does the gravitational force between two objects change as the distance between them increases?

Back

The gravitational force decreases.

Front

What does a scale measure when a person stands on it?

Back

The gravity acting on the person.

Front

Who is credited with the law of universal gravitation?

Back

Newton.

Front

What is the formula for calculating the gravitational force between two masses?

Back

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

Front

What is the significance of the Universal Gravitational constant in physics?

Back

It quantifies the strength of the gravitational force between two objects.

Front

What happens to the gravitational force if the mass of one of the objects is doubled?

Back

The gravitational force between the two objects doubles.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the effect of increasing distance on gravitational force?

Back

Gravitational force decreases with the square of the distance between the objects.
