Physics Work and Energy Worksheet Part I 1. Consider two blocks stacked one above the other on a table. Someone pulls the bottom block to the right with a rope in such a way that both blocks accelerate to the right but no slipping occurs at the interface between the top and bottom blocks. Friction at the interface between the two blocks does
Work & Power Worksheet. Work is done when a force moves an object or changes its direction. It is measured in . Rule for Work . Work = Force (in Joules) (in Newtons) W = F X s . X Displacement (in metres) Power is the rate at which measured in . Rule for Power . Power = Work / Time (in Watts) is done. Power is.
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
