According to the concept of work as it is used in physics, which of the following statements are true? True vA vertical force acts on a mass while it moves horizontally (but not vertically). No work is done by the vertical force. False v The force that a weight lifter applies to the weight does positive work as she holds the weight stationary over her head. Truc vA construction worker pushes on a heavy box of bricks until he is exhausted but the box does not move. No work is done by the force applied to the box. False vA force acts toward the right while the object moves to the left. The work done by the force is negative. True v Positive work is done when a force Is appled perpendlcular to the displacement. Submit Answer You have entered that answer before Incorrect.
