The type of friction that exists when objects are not moving is called static friction.

Here's why:

* Static friction is the force that prevents an object from moving when a force is applied to it. It's like a "holding force" that keeps things stationary.

* Kinetic friction is the force that opposes motion when an object is already moving.

Think of pushing a heavy box across the floor:

* Before you start pushing: Static friction is preventing the box from moving.

* Once you start pushing and the box moves: Kinetic friction is now the force opposing the box's movement.
