Final answer:
The three significant parameters relating to universal gravity and properties of the earth hidden in the acceleration g of every object falling close to the surface of the earth are mass (m), gravitational constant (G), and weight (mg).
Step-by-step explanation:
The three significant parameters relating to universal gravity and properties of the earth hidden in the acceleration g of every object falling close to the surface of the earth are:
- Mass (m): The weight of an object m multiplied by the acceleration due to gravity g is the gravitational force between the object and Earth.
- Gravitational Constant (G): Newton's universal law of gravitation relates the gravitational force to the masses of the objects and the distance between them. The constant G appears in this equation and is a fundamental parameter of universal gravity.
- Weight (mg): The magnitude of the gravitational force acting on an object is given by the weight of the object, which is the product of its mass m and the acceleration due to gravity g.
