Homework Statement


Give a clear example of:
a,) the conversion of elastic potential energy to Kinetic energy.
What elasticky thing can you stretch to propel something?
b.) the conversion of elastic potential energy to GPE
If you stretch that elasticky thing and propel something how do you give it gravitational potential energy?
c.) the conversion of chemical potential energy to KE
What kind of energy is released in a violent, sudden chemical reaction? How would you give kinetic energy to something with that energy?
d.) the conversion of chemical potential energy to thermal energy
When you cause an energetic chemical reaction to occur what usually is the result? Can you think of an example of such a reaction?
e.) the conversion of electromagnetic energy to KE
What kinds of electrical/magnetic devices cause things to move
f.) The conversion of KE to GPE
I will let you figure this one out on your own.

I think you know all these things. Have a little more confidence in yourself. You can do these.
