Your body moving forward when you hit the brakes is an example of inertia. Inertia is the tendency of an object to resist changes in its state of motion. In this case, your body wants to continue moving forward due to its velocity, while the car is decelerating.

A book is resting on a table in a state of equilibrium. Which statement is true about the forces acting on the book? (1 point)
Responses
The force of gravity pulling down the book and the force of the table pushing up on the book are equal.
The force of gravity pulling down the book and the force of the table pushing up on the book are equal.
The book experiences unbalanced forces because the force of gravity pulling down on the book and the force of the table pushing up are equal.
The book experiences unbalanced forces because the force of gravity pulling down on the book and the force of the table pushing up are equal.
The book experiences unbalanced forces from friction, gravity and the table.
The book experiences unbalanced forces from friction, gravity and the table.
The book experiences balanced forces because the force of gravity pushing down on the book is greater.
The book experiences balanced forces because the force of gravity pushing down on the book is greater.

The book experiences balanced forces because the force of gravity pushing down on the book is greater.
The correct statement is:
The force of gravity pulling down the book and the force of the table pushing up on the book are equal.
In a state of equilibrium, the forces acting on the book are balanced, meaning the upward force from the table equals the downward force of gravity.
