What experiments did James Prescott do that caused motion?

Answer 1

James Prescott Joule conducted several key experiments that explored the relationship between heat and mechanical work, leading to the formulation of the first law of thermodynamics. Notably, he famously measured the mechanical equivalent of heat by demonstrating that falling weights could do work to generate heat in a calorimeter. By precisely measuring the temperature rise in the water as a result of the mechanical work done, Joule established the principle that energy can be transformed from one form to another, specifically from mechanical energy to thermal energy, thereby demonstrating the conservation of energy in motion.
