Friction Flashcard

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What are the two types of friction?

Back

The two types of friction are static friction (when an object is not moving) and kinetic friction (when an object is moving).

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object.

Front

Is friction always harmful?

Back

No, friction can be useful, such as when it helps us walk without slipping.

Front

What happens to a toy car on a rough surface?

Back

A toy car will travel shorter distances on a rough surface due to increased friction.

Front

What happens to a toy car on a smooth surface?

Back

A toy car will travel further on a smooth surface because there is less friction.

Front

What is an example of friction in everyday life?

Back

An example of friction is when you rub your hands together to create warmth.

Front

Does more friction increase or decrease speed?

Back

More friction decreases speed.

Front

What is the effect of ice on friction?

Back

Ice creates very little friction, allowing objects to slide easily.

Front

What is the relationship between surface roughness and friction?

Back

Rougher surfaces create more friction, while smoother surfaces create less friction.
