WHAT IS ENERGY?

    Energy is the capacity of doing work.



    You can find energy in everywhere in your daily life. For example, when you get up, you go to the kitchen and turn on the TV, use the microwave and open the fridge. All these home appliances need energy, specifically electric energy, to produce images on the TV, warm the food on the microwave, and keep cold meal on the fridge. When you leaving home, see cars moving throught the road. These cars need energy too, thermal energy, for movement.
