According to this relationship, leaving a 100-watt lightbulb burning for one minute expends 6,000 joules of energy. This is equivalent to the amount of kinetic energy a 1-kilogram rock would have if you dropped it from a height of 612 meters (ignoring air friction). Some Other Forms of ...
Elastic potential energy = force x distance of displacement. W = Fs W = elastic potential energy, in Joules F= force, in Newtons s= displacement, m Because the force is = spring constant x displacement, then the Elastic potential energy = spring constant x displacement squared. F = 1/2 ...
How do we calculate the energy used in heating substances? The energy used to heat a substance can be calculated using the formula: Q = mcΔT, where Q is the heat energy in joules, m is the mass of the substance in kilograms, c is the specific heat capacity of the substance ...

[P]精力the power which one can use in working [U]能,能量,能源the power which can do work, such as drive machines or provide 英英释义 energy[ 'enədʒi ] n. (physics) the capacity of a physical system to do work; the units of energy are joules or ergs ...
Specifies an amount of electric energy in joules, or electric energy per time in watts. Internally, the input inWattorJoule/secondis always converted intoJoule/tick, where 1 second is equal to 60 ticks. This means it uses the following formula:Power in Joule/tick = Power in Watt / 60. ...
F is the Helmholtz free energy in Joules U is the internal energy of the system in Joules T is the absolute temperature of the surroundings in Kelvin S is the entropy of the system in joules per Kelvin Formula development for laws of thermodynamics: ...
Energy is typically measured in Joules (J). Additionally, energy can come in many kinetic or potential forms, all of which can transform into all other types of energy through one or more steps.What is Energy? What is the meaning of energy? Energy is typically defined in science as the ...
