Question

What is the state of an object, if the object is experiencing a net zero unbalanced force?

Answer 1

Step 1: Unbalanced force

1. When the resultant of two opposite forces acting on an object is non-zero and brings it into motion, these opposite forces are called unbalanced forces.
2. When an object is moving with changing speed, the net force on it is unbalanced.
3. SI unit of unbalanced force is $\mathrm{newton}$.

Step 2: An illustrative diagram of the unbalanced force

Step 3: Net unbalanced force is zero

1. When two opposite forces working on an object are equal, the net unbalanced force will be zero and the object will maintain its state.
2. If it was at rest, then it will remain at rest, or if it was moving it will continue moving with constant velocity.
