FLASHCARD QUESTION
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.
2.
FLASHCARD QUESTION
Front
How does doubling one mass affect gravitational force?
Back
If one mass is doubled while the other mass and distance remain constant, the gravitational force increases by a factor of 2.
3.
FLASHCARD QUESTION
Front
What happens to gravitational force if the distance between two masses is halved?
Back
If the distance between two masses is halved, the gravitational force increases by a factor of 4.
4.
FLASHCARD QUESTION
Front
What is the formula for gravitational force?
Back
The formula for gravitational force (F) is F = G * (m1 * m2) / r^2, where 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
What is the gravitational constant (G)?
Back
The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, which is used in the calculation of gravitational force.

FLASHCARD QUESTION
Front
How does increasing the distance between two masses affect gravitational force?
Back
Increasing the distance between two masses decreases the gravitational force, as it is inversely proportional to the square of the distance.
7.
FLASHCARD QUESTION
Front
What is the significance of the center of mass in gravitational calculations?
Back
The center of mass is the point where the mass of an object is concentrated, and gravitational force calculations are based on the distance between the centers of mass of the objects.
