How does the Law of Conservation of Energy apply to a balloon powered car?

Vernita Robberson: Conservation of energy will not really be very useful for this example, because you cannot study all objects involved and know their speed. You might want to better consult conservation of momentum.For instance, all the ejected gas is moving fast backwards, and slams directly in to background air...heating it up. It is very difficult to keep track of all energy in this experiment.The energy is initially stored in the surface tension elasticity of the balloon's rubber, which releases it as kinetic energy of the inside gas....and some of it, because the forces aren't a 1-way street, results in the kinetic energy of the car payload....Show more

Noah Deni: Law of Conservation is a principle that is energy can neither be created nor destroyed; rather, it transforms from one form to another.

Jose Bouliouris: rules of nature shop on with everywhere it is why they're rules of nature. The regulation of conservation of potential/mass (which at the i! nstant are time-honored to be equivallent E= MC^2) applies everywhere interior the unvierse on earth, on different planets, everywhere interior the universe or perhaps the multiverse - if there is one, in the different case it incredibly is not a regulation in any respect.
