Potential energy and work done are the same thing as much as kinetic energy and work done are the same thing. Potential energy is a state of the system, a way of storing energy as of virtue of its configuration or motion, while work done in most cases is a way of chaning this energy from one body to another.
This is because of Convection. Convection is the transfer of thermal energy by the movement of particles from one part of something to another.
the answer is cancer is often named according to what body type it affects
<span>Energy dissipated by friction is E
Initial Ei=mgh
Final Ef=1/2 mv^2
then subtracted Ef-Ei,
ΔE = 0
m g h -- E – 1/2 m v² = 0
66 (9.8) (250) - E - ½ (66)(14)² = 0
E = (9.8)(250) – ((14)^2)/2
E = 155.232kJ</span>
I think it would be clean and store.
