What is the effect of increasing the distance between two objects on the gravitational force?
Increasing the distance between two objects decreases the gravitational force between them, following an inverse square relationship.
What is the effect of increasing the mass of one object on the gravitational force between it and another object?
Increasing the mass of one object increases the gravitational force between it and another object proportionally.
What happens when an object falls from a great height considering air resistance?
The object accelerates until air resistance equals gravitational force, resulting in terminal velocity.

Define Newton's Law of Universal Gravitation.
Every object attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is the gravitational constant (G)?
The gravitational constant (G) is a fundamental constant of nature with a value of approximately $6.67 imes 10^{-11} frac{N cdot m^2}{kg^2}$.
Define gravitational field.
A gravitational field is a field created by a massive object that exerts a force on other objects with mass.
What is a conservative force?
A conservative force is a force where the work done is path-independent, and the total work on a closed path is zero. Gravity is a conservative force.
Define terminal velocity.
Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
