Question

Define balanced and unbalanced force. Why is acceleration of a body not possible under the action of balanced force?

Answer 1

Balanced:-

keeping or showing a balance; in good proportions.

Unbalanced:-

not in equilibrium.

Acceleration of a body is not possible under the action of balanced force because all the forces acting that body results zero.

Answer 2

Answer:

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.Acceleration of a body is not possible under the action of balanced force because all the forces acting that body results zero.
