SUMMARY
The solar wind carries kinetic energy away from the Sun at a calculable rate, which can be expressed in watts and as a fraction of the Sun's luminosity. The kinetic energy (KE) is determined using the formula KE=(1/2)mv^2, where 'm' represents the mass loss of the Sun. The mass loss can be calculated using the equation Msunloss=4πr²vρ, where 'r' is the radius of the Sun, 'v' is the velocity of the solar wind, and 'ρ' is the density of the solar wind. By substituting the appropriate values into these equations, one can derive the solar wind's kinetic energy output.
