One of the most commonly observed phenomena is motion. Even a product traveling from the vendor to the buyer is motion. Velocity can be defined as
“The ratio of number of products sold to the total time taken” and change in such a velocity leads to the acceleration of sales or “fluctuation in sale”. With this the force can be calculated which acts on the product.
Kinetic Energy is the time value of money. Potential Energy is directly related to the profit made on each product.
Product and demand behave like charges in the market. They may attract, repel, become neutral…etc. so the laws of electrostatics hold good here. This gives us space to design the market using the network analysis technique.

Every thing in the world is relative, Absolute motion is meaning less, including the price. Hence “Special Theory of Relativity” can be helpful in solving such a problem.
