1 is B. The magnitude of the gravitational force is the scalar value of the directional vector associated with the gravitational force.





2 is D. Assuming we are dealing with newtonian physics, as opposed to relatavisitc, the answer would be mass. Mass in this context is a measure of the quantity of matter, or more correctly how that matter resists acceleration.





3 is C. weight is the product of a mass and the gravitational acceleration acting on that mass. Therefore, a change in the gravitational acceleration acting on the object would change its mass.
Reply:I think is


B-(weight is mass + applied gravitational potential force)


D-(mass is the original weight of a matter without gravitational potential force) and


C-(as the first one if gravitational force is changed, then mass+ new gravitational force result in a change of weight).
