1.Unbalanced forces always cause a change in motion. They are not equal and opposite.
Balanced forces do not cause a change in motion. They are equal in size and opposite in direction.

2. This is an example of balanced forces. The force exerted by each person is equal, but they are pushing in opposite directions, in this case together. It would look something like this.Because the force that each of you is exerting is equal, the two forces cancel each other out and the resulting force is zero. Therefore, there is no change in motion.

This is an example of an Unbalanced forces.When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces and is exerted in the direction of the larger force.

3.In physics, net force is the overall force acting on an object.
4.Net force is the sum of all forces acting on an object. For example, in a tag of war, when one team is pulling the tag with a force of 100 N and the other with 80 N, the net force would be 20 N at the direction of the first team (100 N - 80 N = 20 N).
