FLASHCARD QUESTION
Front
What does Newton's universal law of gravitation state?
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.
2.
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 universal gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

FLASHCARD QUESTION
Front
What is the value of the universal gravitational constant (G)?
Back
6.67 x 10^-11 N*m^2/kg^2.
4.
FLASHCARD QUESTION
Front
How does mass affect gravitational force?
Back
Gravitational force is directly proportional to the masses of the objects involved; as mass increases, gravitational force increases.
5.
FLASHCARD QUESTION
Front
How does distance affect gravitational force?
Back
Gravitational force is inversely proportional to the square of the distance between the centers of two masses; as distance increases, gravitational force decreases.
6.
FLASHCARD QUESTION
Front
If the distance between two objects is doubled, how does the gravitational force change?
Back
The gravitational force becomes one-fourth of its original value.
7.
FLASHCARD QUESTION
Front
What is the difference between mass and weight?
Back
Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
