Answer 1

Answer:

1. Work is activity involving mental or physical effort done in order to achieve a purpose or result.

2. Positive work and Negative work.

Explanation:

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.

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.
