"As you sit in your chair and study your physics (presuming that you do), the force of gravity acts downward upon your body. The reaction force to the force of the Earth pulling you downward is the force of your body pulling the Earth upwards". I read this somewhere just a bit ago and it's confusing me. How is it possible for you to be able to pull the Earth towards you with the same force? A mathematical explanation would be good also.
