FLASHCARD QUESTION
Front
What is Universal Gravitation?
Back
Universal Gravitation is a fundamental force of nature that describes the attraction between two masses. 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.
2.
FLASHCARD QUESTION
Front
What happens to gravitational force if the distance between two masses is doubled?
Back
The gravitational force decreases to one-fourth of its original value.
3.
FLASHCARD QUESTION
Front
How does increasing the mass of an object affect gravitational force?
Back
Increasing the mass of an object increases the gravitational force exerted by that object.
4.
FLASHCARD QUESTION
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.

FLASHCARD QUESTION
Front
If two masses are moved three times further apart, how does the gravitational force change?
Back
The gravitational force becomes one-ninth of its original value.
6.
FLASHCARD QUESTION
Front
What is the effect of mass on gravitational force?
Back
Gravitational force is directly proportional to the product of the masses; if both masses are doubled, the gravitational force becomes four times greater.
7.
FLASHCARD QUESTION
Front
What happens to the gravitational force if one mass is halved while the other remains constant?
Back
The gravitational force is halved.
