According to classical physics, when an electron accelerated in its circular path, it should lose energy and spiral into the nucleus. Bohr required electrons to physically remain in stationary orbits to prevent this instability, as electrons moving in circular orbits would radiate electromagnetic energy and lose kinetic energy. Therefore, by constraining electrons to stationary orbits, Bohr avoided the classical problem of the electron's energy spiraling into the nucleus.
