Answer:
1.For simplicity, consider no friction between the bottom book and the supporting surface. ... So yes, the friction force applied by the book below it is doing work on the top book.
2.The bob will swing back and forth with the height gradually increasing from its highest possible peak until the bob gradually stops moving. It will remain at rest until a certain force could exerted thus causing the bob to be in motion again.
3.When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.
4.Newton's First Law of Motion states that an object at rest will remain at rest unless acted upon by an unbalanced force. An object in motion continues in motion in the same direction and with the same speed unless acted upon by an unbalanced force. Friction is a force that slows down the motion of a moving object.
