A force exerted on an object is always due to:
AInteraction with another
BThe object's own motion
CThe object's own mass
DThe passage of time
Answer & Solution
Correct answer: A. Interaction with another
1. Forces are not properties an object carries around by itself.
2. A force exerted on an object is always due to the interaction of that object with another object.
3. Forces that systems exert on each other are due to interactions between objects in the systems.
4. That is why every force can be traced back to a specific partner object.
