Question

How will an object at rest be affected if multiple forces working on it are opposed but unbalanced? Responses The unbalanced forces will cause the object to produce a humming sound. The unbalanced forces will cause the object to produce a humming sound. - no response given Motion will be either created, stopped or changed. Motion will be either created, stopped or changed. - no response given The acceleration of the object will increase. The acceleration of the object will increase. - no response given The mass of the object will decrease.

Answer 1

When multiple forces are acting on an object at rest and these forces are opposed but unbalanced, the effect on the object will be that it will accelerate in the direction of the net force. More specifically:

- **Motion will be either created, stopped, or changed.** This is the correct response. The unbalanced forces will result in a net force that can initiate motion if the object is at rest.

The other statements provided do not accurately describe the effect of unbalanced forces on an object:

- The object will not produce a humming sound due to unbalanced forces.
- While the acceleration of the object may increase as it responds to the net force, it is the object’s motion that is most significantly altered.
- The mass of the object does not decrease due to the application of unbalanced forces.

In summary, an object at rest with unbalanced opposing forces will experience a net force that will change its state of motion.
