Physical damage is one of the three types of damage in League of Legends, the others being true damage and magic damage. Physical damage is dealt by all basic attacks, by some champion abilities and by some item effects.
Statistics influencing physical damage
Most physical damage is based on the champion's attack damage (but not all damage based on attack damage does physical damage). The physical autoattack damage is increased by attack speed, critical strike and armor penetration or reduction. A small number of champion abilities that deal physical damage can be strengthened with ability power.
Not all physical damage sources proc life steal, but most that apply on-hit effects do.
Champion abilities dealing physical that don't proc on-hit effects usually proc spell vamp.
The amount of physical damage received is reduced by a certain percentage based on the target's armor or other damage reducing effects, such as 
Alistar's 
Unbreakable Will. The effectiveness of armor can be reduced with armor penetration or reduction.
