First law of thermodynamics for a closed system

WebThe first law of thermodynamics states that the total energy of a closed system remains constant regardless of how it is affected by work or other processes. In other words, when you add heat to a closed system, the total energy will stay the same. But, when you remove heat from a closed system, the total energy will decrease until it reaches zero. WebThe final kinetic energy is the same as the work done as long as the initial velocity is 0m/s. To get a more general answer, we can substitute the expression for the final velocity (√ (v0²+2aΔx)) into the kinetic energy equation Ek=½mv² to get Ek=½m√ (v0²+2aΔx)². This simplifies to get Ek=½m (v0²+2aΔx) emergency preparedness checklist for pets
