Question

consider this situation: a book is sliding to a stop while moving across the classroom floor. of the forces listed, identify which act upon the book. tap to select the forces that are present. normal gravity applied friction tension air resistance check answers

Explanation:

• Normal force: Acts perpendicular to the floor, supporting the book against gravity.
• Gravity: Pulls the book downward towards the Earth.
• Friction: Opposes the book's motion as it slides on the floor.
• Air Resistance: Acts against the book's movement through the air (though usually small compared to friction in this case but still present).
• Applied force: There is no external force being actively applied to the book as it's just sliding to a stop (assuming no one is pushing it anymore).
• Tension: No ropes or strings are involved, so no tension force.

Answer:

Normal, Gravity, Friction, Air Resistance
