1. _____ is the rate at which work is done. 2. When calculating power, you should use the formula P = _____ divided by _____. In this formula, “P” stands for power, ____ stands for work, and _____ for time. 3. The SI unit for Power is the _____. C. Power Problems 4. W = 100 J _____ 5.
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
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)
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.
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.
The work energy theorem states that the change in (a) kinetic energy of a particle is equal to the work done on it by the net force. (b) kinetic energy of a particle is equal to the work done by one of the forces acting on it.
The Basics of Work, Energy, and Power. Objectives: 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.
