Contact force is the force acting on the two bodies in contact in contrast of the different forces..
a)like if a body of mass M is lying on the floor then the downward force Mg is equal to the normal reaction N of the body so here Mg is the contact force.....
b)when two different bodies with masses M and m are in contact and a force F is applied to any body produces a contact force Mg(for mass M) or mg (for mass m)
on the other body...
