Final answer:
When 50J of work is done on an object, its energy increases by 50J, which might increase the object's kinetic or potential energy based on the situation and considering no energy losses.
Step-by-step explanation:
If a total of 50J of work is done on an object, its energy increases by 50J. This can be understood through the work-energy theorem, which states that the work done on an object results in a change in the object's kinetic energy. If there are no other forces doing work (like friction or air resistance) and the object is not gaining or losing potential energy, the entire amount of work translates into kinetic energy.
For example, suppose we have a system where 10.00J of work is done and 4.00J of work is done on the system. The total work done on the system would be 6.00J, illustrating how the energy of the system changes due to the work done on it. Similarly, when 50J of work is done on our object without any losses, the object will have an energy increase of 50J, which could manifest as increased kinetic energy or as potential energy, depending on the circumstances.
