I used a lot of energy this weekend. I went on a run on my dad’s treadmill, using mechanical energy, and electrical energy. I rode my bike, took a walk, used my scooter, all using my mechanical energy. I also used chemical energy, from my food, giving me energy.

Energy is what makes everything happen. It is inside everything, living or not. Chemical energy is in our food, giving us the ability to do work. Mechanical energy is in cars and trains, building up and accelerating. Energy comes in many other forms too such as thermal energy, like the energy we use to cook food.
