The magnitude of the gravitational force acting on an object is weight
Explanation:
In introductory physics textbook, we can find that weight is nothing but a force applied on a given body, by earth's gravity. It is denoted by the formula as,
W = mg
where 'W' is the weight, 'm', is the body's mass, and 'g', the acceleration due to its gravity. When a ball is thrown high into the air, there is no friction. Friction is eliminated. Now, inertia is just a resistant force to change of motion. Hence, the only possibility is weight.
