Universal Gravitation review

Front

As distance between two objects increases, what happens to the pull of gravity?

Back

The pull of gravity decreases.

Front

What does the gravitational force depend on?

Back

Mass and distance.

Front

If two objects are attracted to each other with 125 N of gravitational force, what would the force be if the distance between them were 5 times bigger?

Back

5 N.

Front

What is the relationship between the force of gravity and mass?

Back

The force of gravity is directly proportional to mass.

Front

Why is the sun considered the anchor point of our solar system?

Back

Because of its huge mass.

Front

What is the law of universal 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

How does increasing mass affect gravitational force?

Back

Increasing mass increases the gravitational force.

Front

What happens to gravitational force if the distance between two objects is halved?

Back

The gravitational force increases by a factor of four.

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

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2.
