What is the equation linking pressure difference, depth, density and g

Pressure difference = depth x density x gravity

When a passenger is in the car on a turn. they will most likely slide twords the door. this is because gravity is giving a pushing force twords the way it is turning. this force also acts upon the passenger, causing them to move.
