How does balancing force work?
Forces that are equal in size and opposing in direction are said to be balanced forces. Equilibrium is regarded as a state of balanced forces. There is no change in direction when the forces are in balance. Balanced combined forces are always equal to zero.
Unbalanced force: What is it?
Unbalanced forces are those in which the force acting in one direction is greater than the force acting in the other. A change in speed and/or direction occurs when an object is being affected by unbalanced forces.
