Metals - The close packing of the metal ions in the lattice and the delocalised electrons ensure it can carry kinetic energy through the lattice.
Non - metals have fewer free electrons and electrons are held tightly, meaning they're not allowed to move freely.

The heavier it is the more frictions it creates sliding on the floor. this make more kinetic energy.
