Work Power Worksheet
Work Power Worksheet - These questions & answers will help you master the topic! Determine the work (in joules) done upon the backpack. Calculate the work done by a 47 n force pushing a pencil 0.26 m. A body that has energy may transfer some, or all, of its energy to another body. Web before proceeding, be sure you understand the distinctions among force, work, energy, and power. Hans full is pulling on a rope to drag his backpack to school across the ice. First convert the energy transferred from kj to j. Work can increase energy, and energy can do work. Web these worksheets are provided for private study only and are not to be used for any financial gain. Force exerted on an object over a distance does work.
It is calculated by dividing the useful power output by the total energy input. Web work w and energy e. Causes a body to move, work is being done on the object by the force. Calculate the work done by a 47 n force pushing a 0.025 kg pencil 0.25 m against a force of 23 n. G sandwich across a table 0.75 m. Calculate the work done by a 47 n force pushing a pencil 0.26 m. The body losing energy does work, the body gaining energy has work done on it.
Work done is measured in joules (which has symbol j). Web work w and energy e. Web these worksheets are provided for private study only and are not to be used for any financial gain. The amount of energy transformed (∆e) is called work w. Power is the rate at which work is done.

This collection of pages comprise worksheets in pdf format that developmentally target key concepts and mathematics commonly covered in a high school physics curriculum. Web energy is a key principle in physics, as it allows work to be done. Useful output power e f f iciency (percentage) = input power × 100. A body that has energy may transfer some, or all, of its energy to another body. All the physics revision you need in one place. Where p is the pressure and δ v is the change in volume.
The total amount of energy remains constant (conserved) even if it has been transformed to another type. If 68 w of power is produced in 18 seconds, how much work is done? Each topic of the a level physics specification has a unique worksheet and answers. Web work, energy, and power worksheet. Work = force (in joules) (in newtons) w = f x s.
To define potential energy, to identify the two forms and the variables that affect the Force exerted on an object over a distance does work. Convert the time from hours to seconds. Where p is the pressure and δ v is the change in volume.
Web This Section Covers Work, Energy And Power Using Maths.
These questions & answers will help you master the topic! Force exerted on an object over a distance does work. Work can increase energy, and energy can do work. He pulls upwards and rightwards with a force of 22.9 newtons at an angle of 35 degrees above the horizontal to drag his backpack a horizontal distance of 129 meters to the right.
A Body That Has Energy May Transfer Some, Or All, Of Its Energy To Another Body.
X displacement (in metres) power is the rate at which measured in. Web work w and energy e. Work is done when a force moves an object or changes its direction. Work done is measured in joules (which has symbol j).
Useful Output Power E F F Iciency (Percentage) = Input Power × 100.
The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency. 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. Power = work / time (in watts) is done. The body losing energy does work, the body gaining energy has work done on it.
A Set Of Pulleys Lifts An 800 N Crate 4 Meters In 7 Seconds.
F = 200 newtons formula: Determine the work (in joules) done upon the backpack. Power = work done (or energy transferred) / time taken. How much time is needed to produce 720 joules of work if 90 watts of power is used?
