Radiation, conduction, and convection are methods of energy transfer. of these methods, radiation is the only one in which energy can be transferred through

  empty space.

The other methods of energy transfer make use of the physical motion of the atoms, molecules, or bulk of the medium. Radiation moves energy via electromagnetic waves, rather than physical contact between objects or physical transfer of material.

explanation: well the force of an object when it lands sitting on the ground isthe force of a wide rage of situations crucial to physics? ; ( i 'm trying my best to alot but im not smart enofe you for giving me this chance though! 3(
