Front

What is Sliding Friction?

Back

Sliding friction opposes the direction of an object as it slides over a surface.

Front

Define Fluid Friction.

Back

Fluid friction occurs when a solid pushes a liquid or a gas aside.

Front

How do we measure forces?

Back

Forces are measured in Newtons.

Front

What type of friction is experienced when an object is at rest?

Back

Static friction.

Front

What type of friction occurs when an object rolls across a surface?

Back

Rolling friction.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can slow down or stop moving objects.

Front

What is the difference between static and sliding friction?

Back

Static friction acts on objects at rest, while sliding friction acts on objects in motion.

Front

Give an example of fluid friction.

Back

An example of fluid friction is a boat moving through water.

Front

What is the role of friction in sports?

Back

Friction provides the grip needed for athletes to run, jump, and change direction.

Front

How does surface texture affect friction?

Back

Rough surfaces increase friction, while smooth surfaces decrease friction.
