Hi,
I would like some help with the following question that has been bothering me.
If energy is not created or destroyed then how does the following work:
Consider an asteroid traveling close enough to the Earth to have its trajectory changed due to the gravitational interaction with the earth. The asteroid is far enough so it passes by, and does not fall to Earth or travel through the atmosphere. Energy was used to change its trajectory that is an outcome of the gravitational interaction (force was exerted and work was done). The gravitational field of Earth or the asteroid are not change since they are related to their respective masses which were not changed. In fact you can have a new asteroid travel like that every second with no depletion of Earth’s gravitational field. This seems like unlimited free energy being used.
Any ideas on where the energy that is used to change the trajectory is taken away from? Where do we see depletion in energy?
Thanks for your help.
