Carla demonstrates Newton’s First Law of Motion by slowly pushing a book across a table. The book moves at a constant rate of speed so long as she is pushing it. Which of the following is NOT true?(1 point)

Question

Responses

The forces acting on the book are all balanced.
The forces acting on the book are all balanced.

There is an unbalanced force on the book, acting in the direction of motion.
There is an unbalanced force on the book, acting in the direction of motion.

The upward force exerted by the table balances the book’s weight.
The upward force exerted by the table balances the book’s weight.

Her push balances the force of friction.

Answer 1

The statement that is NOT true is:

There is an unbalanced force on the book, acting in the direction of motion.

This is incorrect because if the book is moving at a constant rate of speed, it means that the net force acting on the book is zero; thus, all forces are balanced. Her push must be balancing the force of friction in this scenario.
