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.

  • Physics -

    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.

    The kinetic energy K of an object of mass m moving at a speed v is defined as K=(1/2)mv^2. It seems reasonable to say that the speed of an object--and, therefore, its kinetic energy--can be changed by performing work on the object. …
