SUMMARY
The kinetic energy (KE) of a 1g (0.001kg) meteor traveling at 30,000 m/s is calculated using the formula KE = 1/2 MV^2, resulting in 450,000 Joules. The calculation confirms that the mass does not need to be multiplied by 4 when velocity is squared; the one-half term is independent of the squared velocity. This clarification addresses common misconceptions regarding the relationship between mass and velocity in kinetic energy calculations.
