Universal Gravitation Review

Front

What happens to the gravitational force between two masses if the mass of either mass is increased?

Back

The gravitational force increases.

Front

How is the radius (r) between two masses measured?

Back

From the center of one mass to the center of the other's center.

Front

Who concluded that the force causing objects to fall to Earth is the same force that keeps planets in orbit around the Sun?

Back

Isaac Newton.

Front

What happens to the gravitational force between two masses if the distance between them is decreased?

Back

The gravitational force increases.

Front

Which scientist concluded that all masses accelerate at the same rate regardless of their differences in mass?

Back

Galileo Galilee.

Front

What is the law of universal gravitation?

Back

It states that every point mass attracts every other point mass 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 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.

Front

What does the gravitational constant (G) represent?

Back

It is a proportionality constant used in the law of universal gravitation, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

How does gravitational force change with distance?

Back

Gravitational force decreases with the square of the distance between the two masses.

Front

What is the significance of the center of mass in gravitational interactions?

Back

The center of mass is the point where the total mass of a system can be considered to be concentrated for the purpose of analyzing gravitational interactions.
