Friction

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 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

Why is friction important in climbing stairs?

Back

Friction helps us grip the stairs, preventing us from slipping and allowing us to climb safely.

Front

What happens when there is less friction on a surface?

Back

When there is less friction, objects can slide more easily, which can lead to slipping or losing control.

Front

Is ice skating an example of high or low friction?

Back

Ice skating is an example of low friction, which allows skaters to glide smoothly.

Front

What is an example of a situation with high friction?

Back

Walking on a rough surface, like gravel, is an example of high friction.

Front

Can friction be both helpful and harmful?

Back

Yes, friction can be helpful (like when walking) and harmful (like when it causes wear on tires).

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

What is kinetic friction?

Back

Kinetic friction is the force that acts on an object that is already in motion.

Front

How does friction affect bowling?

Back

Friction between the bowling ball and the lane affects how the ball rolls and can influence its direction.
