What are the two factors that affect the force of gravity between to objects?
a
Mass and matter
b
Weight and mass
c
Distance and mass
d
Distance and weight
The correct answer is c) Distance and mass.
To understand why distance and mass are the two factors that affect the force of gravity between two objects, let's break it down:
1. Distance: The force of gravity between two objects decreases as the distance between them increases. This relationship is known as the inverse square law. Mathematically, the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
2. Mass: The force of gravity between two objects increases as the mass of either one (or both) of the objects increases. In other words, the more massive an object is, the stronger its gravitational pull on other objects. This relationship is why larger celestial bodies, such as planets or stars, have stronger gravitational forces compared to smaller objects like rocks.
Weight, on the other hand, is a measure of the force of gravity acting on an object due to its mass. Weight is dependent on the mass of the object and the strength of the gravitational field it is in, but it is not a direct factor affecting the force of gravity between two objects.
So, the correct factors that affect the force of gravity between two objects are distance and mass (c).
