The amount of work used to produce energy
A watt is a unit of power - how fast energy is transferred, or in other words, how fast work is done. "Work" can simply be understood as a transfer of certain types of energy.
A1 Mechanical energy is energy produce from raw materials which are burnt, such as oil, work is the use of energy ehich may be mechanical, or physical, which means the use of foods to produce energy which is then used for work, so no, they are not the same thing A2 Energy and work have the same units, ie Joules in the SI system, and the dimensions are Force x Distance, or Newtons x Meters. I always think of work as the use of energy. Thus for example you release energy from a fuel such as gasoline by burning it, and use this energy to do work, ie propelling a car.
Technically, no energy is produced as most electric toasters don't work! Haha!
Greenhouses do not "produce energy".
Energy is the capacity to do work or to produce heat.
energy
Electromagnets do not produce energy at all. They require an electric current to make them work so they are consumers of energy.
Heat is generally considered as a resultant of other energy reactions, which is why it is considered to be related to kinetic energy. All types of energy (the ability to do work) can produce heat energy.
The amount of work used to produce energy
we get all our energy from food as energy can't be produce or destroyed. it can only be used up
Yes. But It can produce very little energy.
No. The whole idea of a home heating system is to produce heat, not to produce work.
Animals produce energy just the same as humans, they release energy to certain body parts and sexual organs sub-consciously. Humans have to release energy to make things work, except you do not think it.
All mitochondria produce energy for the cell. The cell can be considered to be a factory. This factory makes proteins in most cases. The mitochondria produce the energy for the factory to work.
