Answer:
<em><u>1. Work is activity involving mental or physical effort done in order to achieve a purpose or result.</u></em>
<em><u>2. Positive work and Negative work.</u></em>
Explanation:
<u><em>1. Work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.</em></u>
<u><em>2. Positive work is when the force and the displacement are in the same direction and Negative work is when the force and the displacement are in the opposite direction.</em></u>
