Change in thermal energy equation units
WebSep 12, 2024 · The specific heat is numerically equal to the amount of heat necessary to change the temperature of 1.00 k g of mass by 1.00 o C. The SI unit for specific heat is J / ( k g × K) or J / ( k g × o C). (Recall that the … WebThe quantity 1 2 mv 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the translational kinetic energy, KE = 1 2 mv 2, 7.12.
