Question

balanced forces are responsible for which of the following?
keeping an object at rest or maintaining an objects constant velocity
changing the direction of an object
increasing the speed of an object
decreasing the mass of an object

Explanation:

According to Newton's first law of motion, when balanced forces act on an object, the net force is zero. If an object is at rest (\(v = 0\)) and balanced forces act on it, it will remain at rest. If an object is moving with a constant velocity (\(a=0\), since \(F = ma\) and \(F_{net}=0\)), balanced forces will maintain that constant - velocity motion. Changing the direction of an object, increasing the speed of an object implies a non - zero acceleration (\(a=\frac{\Delta v}{\Delta t}
eq0\)), and according to \(F = ma\), a non - zero net force. Mass is an intrinsic property of an object and is not affected by forces.

Answer:

Keeping an object at rest or maintaining an object's constant velocity.
