The result, based on newton's laws, that the net work done on an object is equal to its change in kinetic energy kinetic energy: Fill each grid space with an appropriately concise answer. Work and energy page 1 of 5 please ignore air resistance, treat all surfaces as frictionless unless otherwise specified or implied. If the object is traveling at a constant speed or zero acceleration, the total work done should be zero and match the change in kinetic energy. Box, but in physics the definition of work requires that a force causes a displacement in order for work to be done. If a table were to hold up the same box, it still wouldn't be doing any work. Written by teachers for teachers and students, the physics classroom provides a wealth of resources that meets the varied needs of both students and teachers. >> start new discussion reply. However, since the box is stationary, no work is done. How much work is required to move it at constant speed You must exert a force of 4.5 n on a book to slide it across a table.

Box, but in physics the definition of work requires that a force causes a displacement in order for work to be done. If the total work is positive, the object must have sped up or increased kinetic energy. Question titlework problems iii a. Work and energy page 1 of 5 please ignore air resistance, treat all surfaces as frictionless unless otherwise specified or implied. Be sure to show all calculation work in the space provided. Answers for all kerboodle work aqa gcse watch. Work = force x distance work = 20n x 10m work = 200 j 2) how much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200n? >> start new discussion reply. If the object is traveling at a constant speed or zero acceleration, the total work done should be zero and match the change in kinetic energy. If the total work is negative, the object must have slowed down or decreased kinetic energy. You'll earn badges for being active around the site. The result, based on newton's laws, that the net work done on an object is equal to its change in kinetic energy kinetic energy: If a table were to hold up the same box, it still wouldn't be doing any work.

Go to first unread skip to page: Work and power worksheet answer each question by calculating for the missing variable. The result, based on newton's laws, that the net work done on an object is equal to its change in kinetic energy kinetic energy: Work = force x distance work = 200n x 20m work = 4000 j 3) tommy does 15 joules of … Box, but in physics the definition of work requires that a force causes a displacement in order for work to be done. If the total work is negative, the object must have slowed down or decreased kinetic energy. Our bodies need to use chemical energy to hold the box up, and we are producing a force to keep it in the air. Work = force x distance work = 20n x 10m work = 200 j 2) how much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200n?
