Recall from the laws of motion that force is not required to move an object at constant velocity. Depending on the inertial frame from which the measurement is made, an observer could measure essentially any magnitude and direction for the displacement S.Thus observers in different inertial frames, who will agree on the forces that act on a body, will disagree in their evolution of the work done by the force acting on the body. (c) This power output is higher than the highest value on [link], which is about 35 kcal/min (corresponding to 2415 watts) for sprinting.

This limitation was okay for simple tasks like pumping water or mashing potatoes, but did not work so well for moving a train. Our best tutors earn over $7,500 each month! You need to print out the map sheet on the last page of the assignment instructions. It follows that the increase in energy must be the difference in KE before and after the push. E=25E/4. If a force has a component opposite to the direction of the motion, the work done by that force is negative. Therefore, the water resistance will not depend linearly on the velocity. Work is defined as the amount of energy transferred due to an object moving some distance because of an external force.
