There are several types of contact force:-
If an object is placed flat against an object, then the frictional force will be equal to the weight of the object.
If an object is pushed against the surface, then the frictional force will be increased and become more than the weight of the object.
Tension force:- The tension force is defined as the force that is transmitted through a rope, string or a wire when pulled by forces acting from opposite sides. The tension force is directed over the length of wire and pulls energy equally on the bodies at the ends.
Tension force formula :-
- Frictional force
- Tension force
- Normal force
- Air resistance force
- Applied force
- Spring force

Tension force formula :-
T=mg+ma
where;
T indicates tensign,
m indicates mass,
g indicates gravitational force,
a indicates acceleration.
Normal force:- The normal force is the component, perpendicular to the surface (surface being a plane) of contact, of the contact force exerted on an object.
Example -
If an object hits a surface with some speed, and the surface can withstand it, the normal force provides for a rapid deceleration, which will depend on the flexibility of the surface.
Air Resistance force:- Air resistance force is the force of air pushing against a moving object. Air resistance force is a type of fricoronal fonce. Like all frictional forces, the force of air resistance always opposes the motion of an object. Usually the air resistance force is not very strong.
Air resistance force depends on the speed and the size of the surface area of a moving object.
Example -
When you walk, you are affected by air resistance force, but it does not really slow you down. If you start running, the air resistance force will become more noticeable.
Applied force :- An applied force is a force which is applied to an object by a person or another object. If an person is pushing a desk across a room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
Spring force:- The spring force is the force exerted by a compressed or stretched spring upon any object which is attached to it. An object which compresses or stretches a spring is always acted upon by a force which restores the object to its rest or equilibrium position. For most springs the magnitude of the force is directly proportional to the amount of stretch or compression.
