Question

Which statement best defines work? A. Work is the time it takes to move an object once acted upon by a force. B. Work occurs when balanced forces act on an object and cause movement in the direction of these forces. C. Work occurs when a force causes motion of an object, and this motion is in the same direction of the applied force. D. Work is the distance over time that an object moves once acted on by a force.

Answer 1

a. work is the time it takes to move an object once acted upon by a force

Answer 2

Work is best defined as occurring when a force causes the motion of an object, and this motion is in the same direction of the applied force. Work can be calculated by the following formula: w = fxd or work equals force times distance.
