As we know mass-energy equivalence. But is acceleration also related to energy? If I am inside a jet which has acceleration of 30 m/s2. So the gravitational acceleration is 9.8 m/s2. So we divide 30 by 9.8. We get 3 approx. This means that the pilot is 3 times more heavier when flying the jet. So here acceleration is linked to mass. So what is relation of acceleration with that of mass? Is acceleration same as energy?
