Question

choose the correct answer. when forces are unbalanced and motion occurs, what can be said about net force? it is equal to zero it is greater than zero

Explanation:

To determine the correct answer, we analyze the concept of net force. When forces are balanced, the net force is zero, and there is no change in motion (either at rest or constant velocity). When forces are unbalanced and motion occurs (implying a change in motion, like acceleration), the net force must be non - zero. Specifically, an unbalanced force situation means that the vector sum of all forces (the net force) is greater than zero, as this net force causes the object to accelerate (change its state of motion). The option "it is equal to zero" is incorrect because that would be the case for balanced forces (no change in motion).

Answer:

it is greater than zero
