Initial mechanical energy equation

WebbThe internal energy of an ideal gas is therefore directly proportional to the temperature of the gas. E sys = 3 / 2 RT. In this equation, R is the ideal gas constant in joules per … WebbΔ E diss = W nc,if = Δ ( K + U) if . Step 4: The initial kinetic energy, at yi = 1km, y i = 1 km, is zero. We set the gravitational potential energy to zero at ground level out of convenience. Step 5: The non-conservative work is set equal to the energies to solve for the work dissipated by air resistance.
