By definition, a region of space that contains no matter at all is a vacuum.
a. They are unbalanced
b. They involve more than one object
c. They cause objects to move
d. They cancel each other out
The accurate answer to the question on forces is that they involve the interaction between at least two objects. This is basic to Newton's Third Law of Physics stating that for every action, there is an equal and opposite reaction. Correct option is b.
The correct answer to this forces quiz question is b. They involve more than one object. Physics, specifically Newton's Third Law, states that for every action, there is an equal and opposite reaction. This law implies that a force involves the interaction between at least two objects. The other potential answers are incorrect as forces can be balanced or unbalanced, they may or may not cause objects to move, and they only cancel each other out when they are equal in magnitude but opposite in direction.
