The question "Did the book move? How will you make the book move?" relates to
the physics of motion and friction. Did the book move?
If a book is placed on a surface and left alone, it does not move because no
unbalanced force is acting on it
. The static friction between the book and the surface resists motion. How
will you make the book move?
To make the book move, you must apply a force greater than the maximum static
friction force acting on it. When the applied horizontal force exceeds this
threshold, the book overcomes static friction and starts to move, accelerating
in the direction of the applied force
. The net force must be opposite to the direction of friction for movement to occur. If the applied force is less than or equal to static friction, the book remains stationary
. In summary:
- The book does not move if no force or insufficient force is applied.
- The book moves if you apply a force greater than the maximum static friction force opposing the motion.
This explanation aligns with classical mechanics principles on friction and motion.
