Isaac Newton discovered that force – impact ­– is the result of mass x acceleration. This is why the impact of any statement you make = the size of the idea x the speed of successfully transferring it from your mind to the mind of your customer.Newton also discovered, “For every action there is an equal but opposite reaction.” The faster an advertised offer produces big results, the less well it will work over time.EXAMPLE: When a direct-response offer generates big money quickly, you can be certain that the longer you do it, the less well it will work. To gain attention, a thing must be new, surprising, and different. When it becomes old, predictable, and the-same-as-before, we turn our attention elsewhere.You already know this.Advertising is, in at least some aspects, a science. But systems-focused business owners are demanding that advertising become a science in all its aspects. They say, “Give us fast-acting, reliable advertising that drives ever-increasing sales opportunities,” and the sellers of advertising are saying, “You got it, boss! Coming right up!”I am reminded of the quest for a perpetual motion machine.The first documented claim of perpetual motion was made by Bhaskara of India in the 12th century. It has been followed by countless others. But not one of them has ever worked, and science has proven that none of them ever will.In his book on the subject of Perpetual Motion, Henry Dircks wrote,“A more self-willed, self-satisfied, or self-deluded class of the community, making at the same time pretension to superior knowledge, it would be impossible to imagine. They hope against hope, scorning all opposition with ridiculous vehemence, although centuries have not advanced them one step in the way of progress… The history of perpetual motion is a history of the fool-hardiness of either half-learned, or totally ignorant persons.”When you spend all day, every day talking with enthusiastic young advertising professionals, you meet a lot of people who fit that description.But I promised you a lesson on the Physics of Advertising. Here it is.Newton’s first law of thermodynamics is a version of the law of Conservation of Energy, which tells us that energy can neither be created nor destroyed but can only be transformed from one form to another.EXAMPLE: The chemical energy contained in gasoline can be transformed into kinetic energy, light energy, heat energy, and the percussive energy that you and I call sound, but those energies were there in the gasoline all along.When it is expended, the energy stored in the gasoline is gone. You cannot burn the same gasoline twice.Goodwill, reputation, share-of-mind, and other forms of “buying energy” can be stored in the mind of the customer in 3 different ways.The Performance of your product or service.When you deliver or exceed what the customer expected, you store “buying energy” in the mind of your customer. If you fall short of their expectations, gasoline is burned.A Referral from a friend or an online review.Word-of-mouth is when the buying energy stored in the mind of one customer is shared with another customer. When that word-of-mouth is negative, more gasoline is burned.Stories told in Advertising and by salespeople.Relational energy is built in the mind of the customer when your beliefs are aligned with their beliefs. Some people call this “branding,” but I prefer to think of it as customer bonding. When you create urgency with a limited-time offer, you force your customer into acting “now or never” and gasoline is burned.“Big Money Quickly” happens as the result of urgency; usually a shortage of time, or product, or opportunity. But shout “wolf” too often and the villagers no longer come running....
