Leader. They can also be called a director or conductor.
Answer:
- Last choice: <u><em>The net force on an object applied over a distance</em></u>
Explanation:
When several forces act act over an object, the vectorial force is call net force.
Every force can do work, as the work () is the product of the force () and the parallel displacement (<em>D</em>) caused by such force.
When several works are done on a object the <em>net work</em> is the sum of all the works done by the forces acting on the object.
Such net work is equivalent to a work done by the <em>net force</em> over the net parallel displacement, which is the distance from the starting point and the ending point.
Hence, the net work can be determined as <em>"The net force on an object applied over a distance", </em>which is the last statement.
