Physics in a Pizzeria



I recently got my first job working in a pizzeria and I couldn't help but find myself pondering (not really) all the possible physics involved with such a place. For example, as the pizza goes through the oven, heat is used to cook the pizza. There is a transfer of heat from what heats the oven to the pizza. Then as the customer eats the pizza, there is another transfer of energy as it is eventually used as energy to allow the consumer to do work. All of this holds to the concept of conservation of energy. We can also see physics in the different amounts of work done in order to do the job. Carrying heavy ingredients from the cooler to the kitchen, rolling the dough out, and simply grabbing the pizza to give to the customer. All of these have different work values, depending on the mass and selected distance, but it's a physics concept nonetheless. As we preform the work for all of these tasks, the energy used to do them is transferred to the object which produces the change; the relocation of ingredients, the expanding of the dough, and the customer getting the pizza. This again shows the conservation of energy. We could also go as far as to say that there is physics in when we drop something. Although we would never sell it to a customer, you could measure the velocity at which it fell using kinematics, or the kinetic energy of the object while it falls, or even the force at which it hits the ground. Even if we might not have the free time for these calculations (because it's work) it's just furthur proof that physics is all around us!
