1. The problem statement, all variables and given/known data For science fair, I'm doing a project in which we are trying to calculate the force of a thermometer being moved normally, versus a thermometer being slowed down by a high-friction material. The thermometer will (Potentially) read the amount of thermal energy produced by the friction, and we can then calculate the formula between the force of friction, and the thermal energy produced. 2. Relevant equations Has the formula for the relation between the amount of friction and thermal energy already been experimented and noted? (This is my actual question for the PhysicsForums community) 3. The attempt at a solution Experimentation (Details in part one).
