So, when an object moves in a constant velocity, in a frictional surface, the work we do is the work done against friction instead of change in kinetic energy?

thankyou this is where am confused.

Summary: I am confused in when to use 1/2 e squared k we studied in class that normally, the extension of the spring is directly proportional to the tension applied and we did this question : what is the work that has to be done for a spring to have an extension of length e as the area of the...

Summary: at what circumstances the kinetic energy equation can be applied? My teacher says that, when a constant force is applied and the object moves by d meters, then the work done can be expressed 1/2mv2 where v is the final velocity. But, what happens if the object moves in a constant...
