If a force does a negative amount of work on an object, does the object's speed increase, decrease, or remain the same? Justify your answer.

if a force does a negative amount of work on an object ,so the speed of the object got  decrease  ,because the acceleration  becomes negative  so if the acceleration becomes negative so the speed is decreased.

Explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
