Is work done if you carry a book across the room at a constant velocity?
A. No, the force applied is perpendicular to the direction of motion. B. Yes, the force applied is perpendicular to the direction of motion. C. No, the force applied is parallel to the direction of motion. D. Yes, the force applied is parallel to the direction of motion.
When carrying a book across the room at a constant velocity with the force being perpendicular to the motion, no work is done.
Explanation:
No, the force applied is perpendicular to the direction of motion. When carrying a book across the room at a constant velocity, since the force is perpendicular to the motion, no work is done on the book. Work is only done when there is a component of the applied force in the direction of motion.
