The force which acts on the body can be classified as:
Balanced Force illustration
- Balanced force
- Unbalanced force
Squeeze a rubber ball between the palms of your hands. What do you observe? The shape of the rubber ball changes. The force applied on the ball is equal and opposite, so the resultant of this force does not move the object, instead the object gets deformed as long as the force is applied. This is a temporary deformation.
Here, equal and opposite forces act on a body, and the body is not moving,
so, we can say that the body is in equilibrium (body) or we can also
state as balanced forces acting on an object.
of Balanced force is Zero
Unbalanced force illustration
The figures show a block of wood on a table. When the block is pulled at
point A, it begins to move towards the left and if the block is pulled
at the point B it moves towards the right.
We can observe two things here:
- A force acting on an object changes its speed or direction
- The Resultant of these forces is always greater than zero
Hence the force is said to be Unbalanced
