Explanation:
Detailed explanation-1: -Forces acting on an object may be balanced or unbalanced. When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged.
Detailed explanation-2: -Unbalanced force: If a number of forces acting on an object do not cancel the effect of each other, then the forces are called unbalanced. Also, unbalanced forces when acting on a body, produce acceleration.
