Example Question:
Question: What are the forces acting on a book on a table?
Answer: There are three main forces acting on the book on the table:
1. The weight force, which comes from the book's mass and acts downwards towards the table.
2. The friction force, which comes from the table and acts in the same direction as the book's motion (i.e., upwards).
3. The support force, which comes from the table and opposes any movement of the book (i.e., acts horizontally).
