A Joule-second is equivalent to a (a) watt (b) newton-meter (c) kg.m^2/s (d) N/m (e) none of the above What is the unit of intensity of illumination? Explain, in terms of the definition of power, why energy consumption is sometimes listed in kilowatt-hours rather than ...
The standard abbreviation for kilogram is "kg," and this specificity is critical for maintaining consistency in technical fields. 9 The usage of "kilo" can be less formal and may not always refer to mass. It can be used in various contexts, such as kilojoule (a unit of energy) or kilo...
understand what SHISHKABOB said in his post :) Dave Hehe, just checking my understanding. Weight is the force due to gravity and mass is the amount of matter in an object? And since weight is the force due to gravity, it is considered a force. And this force is measured in Newtons....
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 107ergs, or approximately 0.7377 foot-pounds. What is dyne v...

a box across a room - both are moving the same box the same distance, resulting in the same amount ofworkbeing performed. However, Individual A may move the box in 30 seconds, while Individual B may take 45 seconds to move the box. In this situation, Individual A is shows greaterpower...
Thermodynamicsis the branch of physics dealing with the work and energy of a system. Work, energy and heat all have the same units in physics despite having different meanings and applications. The SI (standard international) unit of heat is the joule. Work is defined as force multiplied by ...
the charging current is 1.2 A") and the charge amassed, or ignored through a circuit a timeframe is communicated in coulombs (in other words "the battery charge is 30000 C"). The connection of the ampere (C/s) to the coulomb is equivalent to that of the watt (J/s) to the joule...
