If the net work done on an object is positive then the object's energy is ...?
The object's energy would also increase since W= energy right? The object's energy wouldn't increase or decrease.
increased. If you do work on an object, its energy increases.
If the net work done on an object is positive, it means that external forces acting on the object are doing work on the object in the direction of motion.
In terms of energy, the work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. So, if the net work done is positive, it implies that the object's kinetic energy is increasing.
Additionally, energy can be transformed from one form to another. If the net work done on an object is positive, it is possible that other forms of energy, such as potential energy or internal energy, are also increasing, leading to an overall increase in the object's total energy. However, without specific information about the system and the types of forces involved, it is not possible to determine the exact changes in these other forms of energy.
