Question

Two or more forces exerted on an object are _______ if their effects do not cancel each other. ​

Answer 1

Answer:

Two or more equal forces whose effects cancel each other out and do not change the motion of an object

Answer 2

Two or more forces exerted on an object are unbalanced if their effects do not cancel each other.

Some Extra Information:-

Balanced force: When the forces acting on a body cancel out effects of each other in such a way that the resultant force is zero, then the forces are said to be balanced. Also, when balanced forces are acting on a body, the acceleration of the body is zero. It is important to note that balanced forces do not produce any acceleration, but these forces may produce a change in shape of a body.

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.
