Thank you so much for answering my questions thus far drwrls. One more,A force of 100 N, acting over a distance of 10 meters, increases the kinetic energy of a moving object by 500 J. This information is sufficient to conclude that the
object accelerated, there was friction present, and the potential energy changed.
It did accelerate since the kinetic energy increased. 1000 J of work was done pusing the object. The remaining 500J of energy could have gone into potential energy or frictional heating, or some of each.
