When multiple forces are acting on an object at rest in opposite directions but are unbalanced, the result is motion. Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In this scenario, the net force is not zero, so there will be an acceleration produced. The direction of the acceleration will depend on the relative magnitudes of the opposing forces.
To calculate the resulting acceleration, you need to know the magnitudes of the individual forces and the mass of the object. Once you have these values, use Newton's second law formula:
F(net) = m * a
where F(net) is the net force, m is the mass of the object, and a is the resultant acceleration.
If the net force is greater than zero, the object will accelerate in the direction of the larger force. If the net force is less than zero, the object will accelerate in the direction of the smaller force. The magnitude of the resulting acceleration will depend on the difference between the magnitudes of the opposing forces and the mass of the object.
In summary, if there are opposed but unbalanced forces acting on an object at rest, the object will experience motion, either being created, stopped, or changed, depending on the relative magnitudes of the forces and the mass of the object.
