* Force can change an object's motion: A force can make an object start moving, stop moving, change direction, or change speed. So, in that sense, a force *always* affects an object's motion.
* Force can be balanced: If multiple forces act on an object and cancel each other out, the object might appear to be at rest. However, the forces are still there, even if their effects are neutralized.
* Force can deform an object: Even if an object doesn't move as a whole, a force can still deform it. Think of pushing on a rubber ball – it squishes but doesn't necessarily move across the floor.
So, a better way to think about it is:
* There's no object that is completely immune to the effects of force.
* If an object appears to be at rest, it's likely that multiple forces are balanced.
* Force can cause changes other than just movement, like deformation.
Let me know if you'd like to explore any of these concepts in more detail!
