What is a non-zero net force?

A force is defined as the push or pull that an item experiences that results in a change in velocity. A vector quantity is force. The Newton is the SI unit of force. A body may be under the influence of numerous forces at once. The net force is the vectorial sum of all these forces. The leftover force is known as the non-zero net force if, after the total, all these forces do not cancel one another out. Assume $F1=F2=F3$, where the magnitudes of the forces are equal. The direction of F1 and F2 are same but $F3$is in the opposite direction. The net force is $F\mathrm{net}=F1+F2-F3Fnet=F2$
