I always though of energy as motion – heat is atoms vibrating and moving, sound is a wave of atoms pushing each other in a specific direction, electricity is the movement of electrons, etc. But I’ve heard that e=mc^2 means energy can become matter and matter can be energy. How can motion become physical matter?
In: Physics
Light is energy, and plants use that to create chemical energy, effectively creating a material that wasn’t there before. They then transport this chemical as sap, and then use it to grow.
You turn chemical energy into body heat and electrical current all day and all night.
