Definition

A force that opposes the movement of one surface against another, often causing heat or wear.

Example

The friction between the tires and the road helps the car to stop safely.

Conversation

I was reading about how friction affects movement in physics class.

That's interesting! I always thought it was just about rubbing things together.

Yeah, but it actually plays a huge role in how things slide or stick.

For sure! Without friction, we would just slide everywhere.

Root Explanation

Friction → It is formed from "frictio" (from Latin, meaning rubbing or rubbing together) and the suffix "-ion" (indicating the action or process). The word "friction" refers to the action of rubbing together, which causes resistance between surfaces.

Memory Tip

Think of the action of 'rubbing together' — that's what friction means, as it describes the resistance that occurs when two surfaces move against each other.
