Energy comes in different forms. Electrical energy can easily be measured in terms of volts and amps, these can be combined to give watts directly. Thermal energy can be measured by the rise in temperature of a fluid or gas being heated, plus the amount of the fluid passing per second. Or if it is being heated by natural gas, you have a gas meter to measure the quantity of gas being used per second or per hour if you like, and the heat content of the gas should be known.. For an internal combustion engine you measure the fuel flow rate, and know the heat content per liter of the fuel.
The richter scale is used by scientists to measure the amount of energy release by an earthquake.
work and energy +++ The Joule (J) is the unit of energy, alone, not of work. The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
Energy of heat = Joules (J)
You can measure distance traveled, energy used or work done.
1 cal is the energy used to heat 1 g of water by 1K
Thermometer is the instrument used to measure average thermal energy.
If you refer to the unit, the international unit for energy is the joule; the symbol is "J".
The unit used to measure the energy of an electromagnetic wave is called a photon.
Joules are used to measure energy. Also the related concept of work, which can be thought of as the transfer of energy.
Nuclear energy is measured in mega electron volts.
Only math can calculate energy.
All energy is measured in joules.
The unit used to measure thermal energy besides joules is the calorie. It is commonly used to quantify the energy content in food and beverages.
Radiometer
The joule.
the calorie
Kilo joules are used to measure the amount of energy stored in food.
