Question

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:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is the net force, \(m\) is the mass, and \(a\) is the acceleration.

Step2: Analyze the condition for motion due to unbalanced forces

When forces are unbalanced, there is an acceleration (\(a
eq0\)). Since \(m>0\) (mass of an object is non - zero), from \(F = ma\), if \(a
eq0\), then \(F>0\).

Answer:

it is greater than zero
