So here it goes. If I am pushing an object, say is shelf. I apply a force of 10N on it, it accelerates, and it exerts 10N back on me. I understand this, but correct me if i am wrong. Now, the shelf also exerts a force of 10N on the air particles while it is moving. Shouldn't the air particles also exert 10N back on the shelf, thereby stopping it? Please kindly explain in simple terms... Thank you!
