# Balanced and Unbalanced Forces

Top
 Sub Topics You could see that a man standing still, a body at rest, a girl having walk, a bus moving and so many things. So there lies a question that what makes a body to be in the state of rest to motion? So comes the balanced and unbalanced force concept. The newtons law explains properly about it.An object at rest will be at rest and the object in motion will continue to be so in the same speed in the same direction unless unbalanced force acts on it. So what are these balanced and unbalanced forces?

## What are Balanced and Unbalanced Forces?

Lets see balanced and unbalanced force definition:
Equal forces when acts in opposite direction on any body the resultant reaction will be zero as these forces cancel out.This is what we call balanced force as the forces are at equilibrium.

Net force = 0
Fig above shows the forces are balanced when book is kept on a table. Here the action force is weight of the book gives out gravity cancels out with the reaction force of the table

When unequal forces acts in the opposite direction these forces will be unbalanced that makes the body to move.This is what we call as unbalanced force as the forces are not at equilibrium.

Net force $\neq$ 0
Fig shows how the forces gets unbalanced when the book is given a push to the left side. Here there is no force to cancel out in right side hence it moves.

## Balanced vs Unbalanced forces

Here are some points where we compare balanced force with unbalanced force:

 Balanced force Unbalanced force Here equal forces acts on body in the opposite direction Here Unequal forces acts on the body in the opposite direction Here net force is zero The net force is not zero The body will be at rest These unbalanced forces make the body to move
