We’ve all heard the term energy at some point in our lives, or on multiple occasions – but what is it and how does it relate to our daily lives? Energy, in simple terms, is the capacity to do things such as work, produce heat or light, and drive motion. Of course, everyone should know that it takes energy to do specific things. If you play a sport, it takes energy for your body to run or dodge the other players. If you go swimming, it takes energy to move in the water. It takes energy for us to do things in our daily lives without us even realizing.
