Describe how a falling object reaches to terminal velocity.At first object falls under the effect of its weight accelerating with g. As it accelerates, air resistance opposing the motion increases therefore resultant force acting on the object decreases and since F=ma, acceleration decreases.
When air resistance becomes equal to weight, forces are balanced so resultant force=0 therefore a=0 and object reaches to terminal velocity.

Explain what is the difference between elastic and plastic behavior.
In elastic behaviour, object recovers its original shape when the forces causing the extension is removed.
In plastic behavior, there is a permanent deformation to the shape of the object when forces are removed.
