Question

Think of a book at rest on a flat leveled surface and another book (same type) that is sliding and slowing down to a complete stop on the

same surface.
a. What force(s) is on the sliding book that is not on the book at rest? Explain why.
b. If the sliding book was speeding up instead, describe how the free body diagram would be drawn differently than the book at rest.

Answer 1

A. What forces is on the sliding book that is not on the book at rest?

The friction between the book and the table and the drag from the air resistance on the book.

B. If the sliding book was speeding up instead, describe how the free body diagram would be drawn differently than the book at rest.

The arrow the direction the book is sliding would be bigger than the others, also be a backwards force from the drag of the air.

Answer 2

A. Friction between the book and the table, drag from the air on the book

B. The arrow in the direction the book travels is larger than the other lines and there would also be a backwards force from the drag
