Universal Gravitation 2

Front

What is the law of universal gravitation?

Back

The law of universal 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.

Front

How does gravitational force change with mass?

Back

If the mass of one or both objects is doubled, the gravitational force between them becomes four times greater.

Front

What happens to gravitational force when distance is doubled?

Back

When the distance between two masses is doubled, the gravitational force becomes one-fourth as strong.

Front

What is the relationship between distance and gravitational force?

Back

Gravitational force decreases as the distance between two masses increases.

Front

What is the formula for 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, and r is the distance between the centers of the two masses.

Front

What does the gravitational constant (G) represent?

Back

The gravitational constant (G) is a proportionality factor used in the equation of universal gravitation, which quantifies the strength of the gravitational force.

Front

If two objects are 3 times further apart, how does the gravitational force change?

Back

The gravitational force becomes 1/9 of the original force when the distance is tripled.

Front

What is the effect of mass on gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction to other objects.

Front

What is the significance of Newton's law of gravitation?

Back

Newton's law of gravitation explains how objects in the universe interact with each other through gravitational forces.

Front

How does gravitational force affect planetary motion?

Back

Gravitational force is responsible for keeping planets in orbit around stars, as it provides the necessary centripetal force.
