Introduction: Understanding Strain in Physics In physics, particularly in the study of elasticity, strain is a key concept. It is a measure of deformation representing the displacement between particles in a material body. Strain quantifies the relative change in shape or size of an object due to externally applied forces or a change in temperature.

An object is said to be in state of motion if its position changes with the passage of time. If the position of the object does not change with the passage of time then the object is said to be at rest. We have now define what is motion and to describe it we consider simplest form of motion that is motion of any object in one dimension for example car moving on the road. To determine the position of car at different times , we could measure its distance from starting point and record all these observations. These observations can be recorded in form of a table or we can draw a distance versus time graph for the motion of the car and see how it is moving.
