Work and energy page 1 of 5 please ignore air resistance treat all surfaces as frictionless unless otherwise specified or implied. Doubling the speed quadruples the kinetic energy so the work by friction to reduce the kinetic energy to 0 make it stop must also increase by a factor of 4. How much work is required to move it at constant speed a 3m along the floor against a friction force of 4n b 3m along a. Work energy solutions energy 1.

Work energy theorem practice problems name ate 5. The number of times n signifies that the particle will come to a rest at the center of the flat. Work and energy the video provides the definition of energy ability to do work and provides an explanation of how work relates to energy. For example on the uss constitution a frigate used in the war of 1812 the cannons were 3 meters 3 mbox meters 3 meters long had a mass of 3000 kg 3000 mbox kg 3 0 0 0 kg and could fire a 10 kg 10 mbox kg 1 0 kg cannonball up to a kilometer away.
