How many joules of work are done when a force of 1 n moves a book 2m?
Exactly 2.6 joules for each meter that you keep pushing it.If the book doesn't move, then there's no work.
How much work was done if a force of 15 N is exerted over a distance of 6 m?
Work = force x distance = 15 x 6 = 90 joules
How much work is done by 4 newtons of force over a distance of 10 meters?
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
Why is it that energy in work are closely related?
Work is equal to Force*Distance.Force*Distance is the Newton Meter and Newton Meter is the same as Joules. So as Joules is the SI unit of energy and thus, also for work. Work is basically the energy exerted to apply a particular force over a distance, and this is their relation according to physics.AnswerEnergy is defined as the ability to do work.Work is defined as the process of converting one form of energy into another. For example, an electric motor does work when it converts electrical energy into kinetic energy.
Describe- how a lever can increase the force without changing the amount of work being done?
Roughly speaking, work = force x distance (the actual definition is a bit more complicated).If you apply 1000 newton over a distance of 1 meter, that involves "work", as defined in physics, of 1000 joules. With a lever, you might apply a lesser force, say, 100 newton, but over a larger distance, in this case, 10 meters. In this case, the product (100 meters x 10 newton) is still 1000 joules.
What does joules mean science?
It is the unit of energy. 1 joules is quantified to energy equivalent to force of 1 Newton act on any object over the length of 1 meter.
How much work is done over 10 meters if the force is 600 newtons?
For a constant force, work = force x distance. In other words, just multiply the two. The answer is in joules.
How much energy can be created from a generator with 100 pounds of force?
The technically correct answer is none. no energy will be created or destroyed, only converted from one type to another. Kinetic energy from a 100 lbs force can be transformed into electrical energy using a generator, however. 100 lbs of force is equivalent to ~445 Newtons, or 445 Joules/meter. So, if a 100lbs force is applied over 1 meter to a generator, it can, at most, produce 445 joules of electricity. The actual produced energy will depend on the efficiency of the generator, and any other losses between the measurement of the 100 lbs of force to the generator. 1 Joule is equivalent to 1 watt second. 445 joules is equivalent to 445 watt seconds, or ~124 milliwatt hours (if you want to relate it to your electric meter).

Is joules equal to power?
It is the unit used to measure energy or work. The definition is that one joule is equal to the energy used to accelerate a body with a mass of one kilogram, using one newton of force, over a distance of one meter

How much work is done when a 115 g tomato is lifted 14.5m?
Work = Force applied over distance. So, distance is 14.5m, but how much force is applied? Force is equal to mass times acceleration, usually due to gravity. So, the force the tomato applies is .115kg * 9.81 m/sec2 = 1.12 Newton's. The work then is 16.2 Joules.
How much will a body of mass x accelerate with energy equal to 31315135800000000 K joules?
W=Fx (work =force times displacement) W=MAx (since F-ma) therefore Acceleration =31315135800000000/(Mass multiplied by the distance over which the force is applied)
