A Contact force is a force applied to a body by another body that is in contact with it. Contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. Contact force is governed by Newton’s Laws.

Examples :: Contact force is responsible for most of the interactions we experience in the daily life.

1. Writing your name with a pen, pushing a car up a hill, lifting an object, etc...

2. Kicking a ball, hammering a nail, etc...

are some of the everyday examples where contact forces are at work.

In the first case, the force is continuously applied by the person on the car or pen or an object while in the second case the force is delivered in a short impulse.

Contact forces are often decomposed into orthogonal components

one perpendicular to the surface in contact called the normal force, and

one parallel to the surface in contact, called the friction force.

In the light of competition, it may be seen that competitors may initiate price changes. If the cutting off on prices does not affect the company, then the current pricing strategy itself can be continued to maintain the profitability of the company. However if the price change on one firm is affecting the other, then it can:

a.reduce the product price at par with competitors’ price or below competitors’ price

or

b. Provide added advantage to the existing product like better quality, or ‘a buy one get one free’ offer.

or

c.Provide better quality of the product at a higher price thereby not being at par with the competitors.
