Answers
Acceleration due to gravity.
Attraction between two objects is due to gravitational force.
Answer:
The property of earth which is responsible for extremely small acceleration being produced in it as a result of attraction by other small objects is the huge amount of mass of the earth.
The mass of the earth is 5.972 × 10^24 kg.
Explanation:
We know the greater the mass of a planet or a star, the greater the gravity of the planet or the star.
Newton's universal law of gravitation is: F = Gm1m2/r²
As we can see in Newton's universal law of gravitation formula, the force of attraction between two object is directly proportional to the gravity of the objects. As the earth has greater mass, so that it has greater gravity. So the mass of the earth is responsible for extremely small acceleration being produced in it as a result of attraction by other small objects.
