question 1\na force consists of\n a push or pull that is inflicted upon an object by another source\n a mass and an impact\n two objects in contact with one another\n two invisible objects
Answer
Brief Explanations:
Force is defined as a push or pull exerted on an object by another source. Mass and impact are related to force - mass is involved in the calculation of force (F = ma), but they do not define what a force is. Just two objects in contact or two invisible objects do not fully define force.
Answer:
A. a push or pull that is inflicted upon an object by another source
