Step 1
Hammering a nail: The energy is conserved in this activity by transforming from one form to another. The kinetic energy of the moving hammer is transferred to the nail, causing it to move (also kinetic energy). Some of the energy is also converted into heat due to Show more…

Describe how energy is changed from one form to another in these processes: (a) At a July 4 th celebration, a match is lit and ignites the fuse of a rocket firecracker, which fires off and explodes at an altitude of $1000 \mathrm{ft}$. (b) A gallon of gasoline is pumped from an underground storage tank into the fuel tank of your car, and you use it up by driving $25 \mathrm{mi}$.
Identify the energy conversions taking place in each of the following situations. Name all of the relevant forms of energy that are involved. (a) A camper rubbing two sticks together to start a fire. (b) An arrow shot straight upward, from the moment the bowstring is released by the archer to the moment when the arrow reaches its highest point. (c) A nail being pounded into a board, from the moment a carpenter starts to swing a hammer to the moment when the nail has been driven some distance into the wood by the blow. (d) A meteoroid entering Earth's atmosphere.
State the law of conservation of energy. Describe how it explains the motion of a child on a swing.
