Answer:
The radiated heat from the kinetic energy is transferred speedily across the blade but not in the wood.
Explanation:
The moving saw blade is a metal and metals are very conductive as they have free valent electrons in their outermost shell. So the heat is transferred from the action point to the other end of the saw blade.
Unlike the saw blade, the wood is a poor conductor of heat and would slowly absorb the heat which may not translate the entire wood before the sawing is complete.
