Question

What is an unbalanced force? Give two examples.

Answer 1

Answer:

If the resultant force of all the forces

acting on a body is not equal to zero, then the body

will not be in equilibrium. Such forces are called

Unbalanced forces.

Example:

1. Drawing water from a well.
2. force  applied with a crow bar.
3. forces on a weight

balance.

Answer 2

A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size, is known as an unbalanced force. In an unbalanced force, a body changes its position i.e. we can observe a moving object changing its direction, either increasing the speed or decreasing the speed and a body at rest starts to move and vice versa.
