What is the formula for a Joule?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
In practical terms, even a small force can do a lot of work if it is exerted over a long distance..
What does 200 joules mean?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
How many volts is 200 joules?
1 Electron volt (eV) = 1.602176565 x 10-19 joules (J)….Please share if you found this tool useful:Conversions Table5 Joules to Electron Volts = 3.12075467163E+19200 Joules to Electron Volts = 1.24830186865E+216 Joules to Electron Volts = 3.74490560596E+19300 Joules to Electron Volts = 1.87245280298E+2113 more rows
How many joules is 1 kg of wood?
14.9 megajoulesA common hardwood, red oak, has an energy content (heat value) of 14.9 megajoules per kilogram (6,388 BTU per pound), and 10.4 megajoules recoverable if burned at 70% efficiency.
How much energy is in 1 kg of uranium?
It’s done through a process called nuclear fission, where uranium atoms are split into smaller atoms to produce electricity. The potential power locked inside a uranium atom is mind-boggling. 1 kg of coal will give you 8 kWh of heat, whereas 1 kg of uranium-235 will create a ridiculous 24,000,000 kWh.
How do you convert kg to energy?
This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short. The joule is not a unit of energy that is used much in everyday life.
What do you mean by 1 Joule?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. … Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
How much energy is in 1kg of coal?
With a complete combustion or fission, approx. 8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235. Related to one kilogram, uranium-235 contains two to three million times the energy equivalent of oil or coal.
How many joules are in a kg?
89,875,517,873,681,764 joulesOne kilogram (kg) of mass is equivalent to exactly 89,875,517,873,681,764 joules (according to E=mc2 with m = 1 kg and speed of light c = 299,792,458 m/s).
What is 200 joules in KG?
Convert 200 Joules to Kilogram-force Meter200 Joules (j)20.39 Kilogram-force Meter (kgfm)1 j = 0.101972 kgfm1 kgfm = 9.81 j
How many joules are in a gram?
The answer is 4.1858. We assume you are converting between joule and gram calorie. You can view more details on each measurement unit: joules or gram calorie The SI derived unit for energy is the joule. 1 joule is equal to 0.23890295761862 gram calorie.
What does E mc2 mean?
E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
How many joules are in 1 kg of coal?
29,307,600 joulesOne kilogram of coal contains 29,307,600 joules of energy.
What is E mc2 used for?
Einstein’s equation E = mc2 shows that energy and mass are interchangeable. The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light.
Why is speed of light squared?
The reason is that energy, be it light waves or radiation, travels at the speed of light. … But why is the speed of light squared? The reason is that kinetic energy, or the energy of motion, is proportional to mass. When you accelerate an object, the kinetic energy increases to the tune of the speed squared.
