The work that a force does by acting on an object is equal to what?

1) the product of force (in the direction of motion) and distance and is negative if the force and motion are in the same direction

2) the product of force (in the direction of motion) and distance and is positive if the force and motion are in the same direction

3) the product of force and distance without regard to direction

4) the product of distance and kinetic energy

5) the product of momentum and force (in the direction of motion)

1. No way I am going to just say what the answer is. You have to know and it is in your text or in any online definition of mechanical work done. Try to answer.
