FLASHCARD QUESTION
Front
Back
F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.
2.
FLASHCARD QUESTION
Front
If the distance between two objects is halved, how does the gravitational force change?
Back
The gravitational force increases by a factor of 4, since force is inversely proportional to the square of the distance.
3.
FLASHCARD QUESTION
Front
What is the gravitational constant (G)?
Back
G = 6.674 × 10^-11 N(m/kg)^2, a constant used in the calculation of gravitational force.
4.
FLASHCARD QUESTION
Front
Define gravitational force.
Back
Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between them.
5.
FLASHCARD QUESTION
Front
What happens to gravitational force if one mass is doubled?
Back
The gravitational force doubles, as it is directly proportional to the masses involved.
6.
FLASHCARD QUESTION
Front
What is the effect of increasing the distance between two objects on gravitational force?
Back
Increasing the distance decreases the gravitational force, as it is inversely proportional to the square of the distance.
7.
FLASHCARD QUESTION
Front
Calculate the gravitational force if two 5 kg masses are 2 meters apart.
Back
F = G * (m1 * m2) / r^2 = (6.674 × 10^-11) * (5 * 5) / (2^2) = 8.34 × 10^-11 N.
