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 happens to objects in motion without friction?

Back

Without friction, an object in motion would never stop.

Front

What is the effect of a rough surface on friction?

Back

Rough surfaces create greater friction compared to smooth surfaces.

Front

What is the effect of a smooth surface on the movement of objects?

Back

Smooth surfaces reduce friction, allowing objects to move further.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the Earth, preventing them from floating.

Front

What would happen if there was no gravity?

Back

Everything would float.

Front

Which surface allows a toy car to travel the furthest?

Back

A toy car travels furthest on ice due to low friction.

Front

Why is friction important for writing?

Back

Friction helps you write on paper or a blackboard by providing grip.

Front

What is an example of a surface with high friction?

Back

Carpet is an example of a surface with high friction.

Front

What is an example of a surface with low friction?

Back

Ice is an example of a surface with low friction.
