In this video, this guy explains Newton's third law. This 3rd law is every object that has an action also has a reaction. This means if the earth pulls me, I pull the earth too. Another example is an apple in my hand. I push the apple up and it pushes my hand down.
This video the guy explain more examples of how it's all connected. It's a really great video to go by and helps if you ever need help in this area of Physics. He explains the law, shows examples of most-all action and reaction pairs, with their vectors. Vectors are the arrows you see in the examples that show which way or how much of the force is happening in a certain direction. If you need more help with the 3rd law just watch this video!
I like it because it's straight forward. Personally I would rephrase the law to state that every action has a reaction because technically objects don't have actions and reactions, it's a relationship not a possession.
