Question

choose the correct answer. what is the best definition of work? when the net force on an object is zero. when an object stays stationary and does not move. when an object moves a distance due to a specific force.

Explanation:

In physics (a subfield of Natural Science), work is defined as the product of force and the distance moved in the direction of the force. So work is done when a force causes an object to move a distance. The first option describes equilibrium (net force zero, no work if no motion), the second option has no motion so no work. The third option matches the physics definition of work.

Answer:

C. When an object moves a distance due to a specific force. (Assuming the options are labeled A, B, C as per the order: A. When the net force on an object is zero. B. When an object stays stationary and does not move. C. When an object moves a distance due to a specific force.)
