which best summarizes a concept related to the work - energy theorem?\nwhen work is positive, the environment does work on an object.\nwhen work is negative, the environment does work on an object.\nwhen work is positive, the kinetic energy in a system remains constant.\nwhen work is negative, the kinetic energy in a system remains constant.
Answer
Brief Explanations:
According to the work - energy theorem, the net work done on an object is equal to its change in kinetic energy ($W_{net}=\Delta K$). When work is positive, the net work done on the object is positive, which means the environment is doing work on the object and its kinetic energy increases. When work is negative, the object is doing work on the environment.
Answer:
When work is positive, the environment does work on an object.
