Where Does The Energy For Animals Come From
Where does free energy come from? Where does free energy go?
Free energy can be found in many things and takes many forms. There is potential free energy in objects at residual that will make them move if resistance is removed. There is kinetic free energy in objects that are moving. The molecules making up all matter contains a huge amount of energy, as Einstein's E = mc^ii pointed out to the states. Energy tin likewise travel in the course of electromagnetic waves, such as heat, lite, radio, and gamma rays. Your body is using metabolic energy from your terminal repast as you read this. Energy is constantly flowing and changing form. If yous accept your metabolic energy and rub your easily together, y'all have fabricated metabolic energy into mechanical free energy. Your hands volition rut up. That is some of the mechanical free energy turning into heat free energy.
So energy can change grade, but where did that free energy ultimately come up from? Let's trace back a chain of events. A bicycle is rolling down the hill, transferring potential energy into kinetic (move) energy. The bicycle got its potential energy (energy due to position related to gravity) by the passenger using metabolic energy to move the pedals. The pedals used mechanical free energy to move the chain, which moved the wheels. The rider'south metabolic energy came from chemical energy that was stored in the molecules of the food she ate. That chemical energy entered the animal whose meat she ate by the animal digesting a plant and breaking the bonds in its molecules. The plant made the molecules by using light free energy from the Lord's day. The Sunday's light energy came from electrons in its atoms lowering energy states, and releasing energy. The energy in the atoms came from the nuclear reactions in the centre of the Sunday. What started the nuclear reactions? Physicists think the Big Bang did.
And so the short answer is that the energy nosotros encounter and employ everyday has always been with us since the showtime of the universe and always will be with us. It merely changes form all around usa. That is called the constabulary of conservation of energy.
What is heat?
Where does DS1 become its electricity?
How much power is bachelor for the communications arrangement?
What is resistance?
What role does the Lord's day play in space missions like DS1's?
