was just watching this video(The joy of science) on thermodynamics, and the proffesor of the video said "hot objects don't always accelerate." this went against what i previously thought. tried googling it but couldn't find an answer. i don't know how to picture this. how?
 
Physics news on Phys.org
not sure if i put his statement out of context, but after he mentioned it he went to go on and explain work = acceleration x distance.
 
That is a strange quote, of course hot objects don't always accelerate. If they did then your stove would have to chase your pot in order to boil water. I don't know what they were trying to express.

By the way, work=force.distance not acceleration. If you push a box along the ground you do work, but if the friction force is equal to your pushing force there will be no acceleration despite all the work you do.
 
ok thanks i just realized what a dumb question that was, because the heat can go at a constant flow. thanks
