To select the two variables that affect the strength of gravity between objects, we need to understand the factors that determine gravitational force.
The formula for the gravitational force between two objects is given by Newton's law of universal gravitation:
F = (G * m1 * m2) / r^2
Where:
- F is the gravitational force between the objects
- G is the gravitational constant (approximately 6.674 × 10^-11 N m^2/kg^2)
- m1 and m2 are the masses of the two objects
- r is the distance between the centers of the two objects
Based on this formula, we can determine the two variables that affect the strength of gravity:
1. Mass: The gravitational force is directly proportional to the mass of the objects. Higher mass objects will exert a stronger gravitational force on each other compared to objects with lower mass.
2. Distance: The gravitational force is inversely proportional to the square of the distance between the objects. As the distance between the objects increases, the gravitational force decreases. Therefore, objects that are closer together will experience a stronger gravitational force compared to objects that are farther apart.
So, the two variables that affect the strength of gravity between objects are mass and distance.
