When a book is resting motionless on a table, what does this situation demonstrate about the forces acting on it?

The force of gravity is the only force acting on the book.

There are no forces acting on the book at all.

Multiple forces are acting on the book, but they cancel each other out.

The upward push from the table is significantly stronger than the downward pull of gravity.

Imagine a lamp hanging from the ceiling by a cord. Which statement best describes the primary forces involved?

The cord pulls the lamp up, and gravity pulls the lamp down.

Only the force of gravity is acting on the lamp, pulling it downward.

The ceiling pushes the lamp up, and the air pushes the lamp down.

There are no forces acting on the lamp because it is not moving.

The book has no mass, so gravity does not affect it.

The table exerts an upward force that counteracts the downward pull of gravity.

The force of air pressure existing below the book is strong enough to hold it up.

Gravity stops acting on the book once it makes contact with the table's surface.

A baseball flying through the air after being hit by a bat.

A car parked on a level street.

A rocket accelerating upward after launch.

They act in the same direction.

They act in opposite directions.

The pull of gravity is much weaker.
