Work and Power. 1. Calculate the work done by a 47 N force pushing a pencil 0.26 m. 2. Calculate the work done by a 47 N force pushing a 0.025 kg pencil 0.25 m against a force of 23 N. 3. Calculate the work done by a 2.4 N force pushing a 400. g sandwich across a table 0.75 m wide. 4.
The Work–Energy Theorem begins to answer that question by stating that a system gains or loses kinetic energy by transferring it through work between the environment (forces being POWER
The Basics of Work, Energy, and Power Objectives: 1. To describe the conditions under which positive and negative work are done and to use the work equation to calculate the amount of work done. 2. To define potential energy, to identify the two forms and the variables that affect the
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.
PF1.5: WORK, ENERGY AND POWER. Energy exists in many different forms, eg, kinetic energy Ek, potential energy Ug, electrical energy, and elastic (or spring) energy Es. A fundamental principle of nature is that energy cannot be created or destroyed, only transformed or transferred.
4.1 Use the work-energy theorem to calculate the magnitude of the velocity of the bullet -block system immediately after the bullet strikes the block, given that the frictional force between the block and surface is 10 N. (5)
