what is energy? what is its SI unit?how can it be measured
Answers
Answer:
Since energy and work are two sides of the same coin, they are measured with the same units. The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 - 1889)
Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

For example, 1 gram calorie is equivalent to 4.186 joules, which is used to measure heat energy. ... One calorie is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
