Effects of Force on Shape of Object

When force is applied on object, it causes the change in shape of object. This change in shape is called deformation. Deformation is of two types depending on duration of change in shape

Elastic Deformation

In elastic deformation, change in shape of object is temporary. The object regains its shape as soon as the force is removed. For example when steel is subjected to load it deforms elastically and regain it shape when load is removed. This can be best explained by Hooke’s Law in Stress and Strain Curve.

Plastic Deformation

When force is applied on object and shape of object changes permanently, it is called plastic deformation. Consider the above example, if in the above case the load is not release and we continue the load, the shape will deform permanently and initial shape will not be regained.

Effects of Force – Concept and Examples

Force is a push or pull acting on a body. In day to day life, we encounter powerful effects of force all around us. From walking, lifting, writing, closing and opening of doors, we are surrounded by the effects of force. It is one of the fundamental physical phenomena. We can’t imagine our lives without force. Even planetary motion and various other natural activities are guided by the force.

In this article, we are going to learn about effects of force with a basic introduction of force and its types.
