Some included gravitational force, centripetal force, and even buoyancy force due to a fluid. But there is also another force that is just as important and that deals with...

## Important Thermal Properties in Physics

Two of the most important thermal properties in physics are thermal conductivity and heat capacity. It is the reason why objects are cold on one end and eventually heat up to a certain temperature after a certain time. Notice however that some objects heat up more quickly than others. We’ll talk about how...
