Is a Joule equal to a Newton*(m)? By amdewster — On Jul 12, 2013 How many joules are required to cause air (and water) to break down into plasma? Anybody? By anon301292 — On Nov 03, 2012 what is kinetic energy? By anon301277 — On Nov 03, 2012 Watts are never equi...
Joule is the unit of energy used by the International Standard of Units (SI). It is defined as the amount of work done on a body by a one Newton force that moves the body over a distance of one meter. Wait a minute … is it a unit of energy or a unit of work? Actually, it ...
One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (exactly) 6.24150974 × 1018 eV 0.2390 cal (gram calories) 2.390 × 10-4 kcal (food calories) 9.4782 × 10-4 BTU Units defined exactly in terms of the joule include: 1 thermochemicalcalorie = ...
A watt is a unit of power that measures the rate at which energy is consumed or produced. One watt is equal to one joule per second and is denoted by the symbol "W." On the other hand, a watthour is a unit of total energy consumed or produced over a specific period of time. One...

Joule's heating effect, also known as resistive heating, states that when an electric current passes through a conductor, it generates heat. The amount of heat produced (H) is directly proportional to the square of the current (I), the resistance (R) of the conductor, and the time (T)...

Part of the problem is that while the system is technically underdetermined, there are not that many degrees of freedom to spare to ensure this underdetermined nature, so one cannot afford to make an ansatz that sacrifices too many of these degrees of freedom. In my previous paper I was ...
The joule (symbol: J) is the basicSI unitofenergy. A joule is equal to thekinetic energyof a kilogrammassmovingat the speedof one meter per second (one joule is a kg⋅m2⋅s−2). Alternatively, it is the amount of work done on an object when a force of onenewtonacts in the ...
