two people push on the same door from opposite sides as shown. they will only see the door move when both people exert the same force so that the forces are unbalanced. neither person exerts a force on the door so that the net force is zero. one person exerts more force than the other so that the forces are unbalanced. both people exert the same force so that the forces are balanced.
Answer
Explanation:
Step1: Recall force - motion relationship
When forces acting on an object are balanced, the net force is zero and the object remains at rest or in uniform - motion. When forces are unbalanced, there is a non - zero net force and the object accelerates.
Step2: Analyze door's motion
For the door to move, there must be a non - zero net force acting on it. When two people push on the door from opposite sides, if one person exerts more force than the other, the forces are unbalanced and there is a net force causing the door to move.
Answer:
one person exerts more force than the other so that the forces are unbalanced.
