Work Power Worksheet
Work Power Worksheet - Calculate the work done by a 47 n force pushing a pencil 0.26 m. Then the work done by the force is the component of f in the direction of motion × the distance the body moves as a result. The amount of energy transformed (∆e) is called work w. The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency. Useful output power e f f iciency = input power. Web these worksheets are provided for private study only and are not to be used for any financial gain. Each topic of the a level physics specification has a unique worksheet and answers. Suppose a force f acts on a body, causing it to move in a particular direction. Work, energy, and power study notes, worksheets with answers (pdf), individual study notes and summary revision notes for ib physics hl/sl. Web power worksheets, questions and revision for gcse combined science and physics.
How much time is needed to produce 720 joules of work if 90 watts of power is used? Hans full is pulling on a rope to drag his backpack to school across the ice. Work = force (in joules) (in newtons) w = f x s. The total amount of energy remains constant (conserved) even if it has been transformed to another type. Where p is the pressure and δ v is the change in volume. Convert the time from hours to seconds. The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.
Work done is measured in joules (which has symbol j). Work can increase energy, and energy can do work. Calculate the work done by a 47 n force pushing a 0.025 kg pencil 0.25 m against a force of 23 n. The total amount of energy remains constant (conserved) even if it has been transformed to another type. The body losing energy does work, the body gaining energy has work done on it.
