Question 1 • 350CR Integrated Science
Work is done when a force causes an object to move in the direction of the force, or has a component in that direction. The mover does work carrying the box upstairs, the wind does work moving the pool chair, and the weightlifter does work lifting the barbell. The box on the table and the held barbell do not move, and the anchored table does not move, so those situations involve no work on the object.
