A book is resting on a table. It has several forces acting on it, one of which is the force of gravity from the Earth pulling on the book. Describe the force acting upwards on the book, and discuss the action-reaction pairs that exist for both of these forces.

Which of the following is NOT correct about action and reaction forces?Group of answer choicesan example could be the recoil of a gun after the bullet has been firedan example could be pushing the ground back with our feet, so that ground pushed us forward and we can walkan example could be the upward movement of a balloon after the air has been releasedAll these statements are incorrectAction and reaction are equal and opposite forces and cancel each other.
