Contact and Non Contact Forces
Rigid object and Non Rigid Object
2
What is a Rigid Body?
On applying force on this body, its shape remains unchanged.
A force cannot change the interspacing between its constituent particles.
Force cannot change the dimensions of the body it can produce onle motion in it.
3
What is a non rigid Body?
On applying force on this body, its shape remains unchanged.
A force cannot change the interspacing between its constituent particles.
Force cannot change the dimensions of the body it can produce onle motion in it.
4
What is contact force?
Force being applied on two bodies which are physically touched
examples :-
frictional force , normal reaction foce, Tensional force, force exerted by spring, force exerted during collision

Box suspended from a support by means of a string
the two forces acting on it are :- weight of the box acting vertically downwards and tension force acting vertically upwards
t = w
10
If a spring is stretched
its length increases and it possesses elastic potential energy
on releasing it it regains its orginal shape due to its elastic nature and restoring force

Name A device based on the priciple of restoring force in spring ?
Spring Balance

What is non-contact force?
Force being applied on two bodies which are not in physical contact ( action at a distance force)
examples :-
Gravitational force , electrostatic force, magnetic force,
