An apple is a favorite example to illustrate a one joule of work when using the definition given earlier (i.e., the amount of work done ….) because an apple weighs approximately one Newton. Thus, you’d have to exert a one Newton upward force to counteract its one Newton weight. Once...

A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules.
What is a joule? What are the units of electric field? What is the unit of electrical resistance? What is the unit of work? What is unit weight? What is the unit of electric charge? What is the unit of electrical current? What is the CGS unit of energy?
Joule. Like all SI units, the letter of its symbol is written in upper case, yet is in lowercase when it is spelled out in English. Advertisements Techopedia Explains Joule A joule is defined as the amount of energy transferred to an object when a force of one newton acts on the ...
What is equivalent to one Newton unit? 1) To convert 1.8 h to minutes, by what conversion factor should you multiply? 2) What determines the precision of a measurement? What are 0.43 minutes converted into seconds? What is the SI unit of work?
A joule is a unit of energy or work. One joule is the work needed to move one ampere through one ohm of resistance for one second. In the example, energy will be required to pump the molasses past the kinks and out through the end. This energy could be supplied by a battery (in ...
where P is power, W is the work done and t is time. Watts are the more common term for measuring power which is why the conversion to and from horsepower is good to know. One watt is 1 joule/second. And that can be converted to … well, you’ll have to do the rest of that ...
Well, here is how: Let’s say that Power (P) = Work x time – 1 = Joule x second -1 ……. (Step 1) Since, Work = Force (M x a) x displacement = M1 L2 T-2L Hence, the dimensional work formula = M1 L2 T-2…… (Step 2) By substituting equation two into equation one,...
The unit is named after the English physicist James Prescott Joule, whose work led to the theory of conservation of energy, and the first law of thermodynamics, in the 19th century. Through his experiments, he was able to determine that energy changes from one form to another when work is ...
