Energy change in planets

  1. Sep 10, 2010 #1
    In case mars jumps from it's orbit to earth's,then will it lose it's energy
    in electromagnetic radiation form or something else happens?
    I found from Doc AL that only charged particle loses energy in electromagnetic form.Then in which form will it lose it?

    In your scenario what made Mars jump?

    lets not talk about 'mars jumping'.In a eliptical orbit,the planets have a different energy & when the planet moves from higher energy position to lower energy position,in which form does it lose it?Is it electromagnetic or something else?

    In an elliptical orbit the satellite speeds up as it moves closer in, exchanging potential energy for kinetic energy.

    u mean energy remains constant.
    But if there is any energy change takes place,how will the planets lose it?

    It depends on what causes the change to take place, such as a collision with another body. It doesn't take place by itself, in contrast with charged particles.
