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 the two main factors that determine the amount of friction between two objects?

Back

The amount of force applied and the roughness of the surfaces in contact.

Front

In which direction does friction act in relation to movement?

Back

Friction acts in the opposite direction of movement.

Front

How does increased friction affect the speed of an object?

Back

Increased friction decreases the speed of an object.

Front

Why do basketball players wear shoes with tread?

Back

To increase friction between the floor and the player’s feet, helping them to stop and change direction more effectively.

Front

What type of surfaces have greater friction?

Back

Rough surfaces have greater friction compared to smoother surfaces.

Front

What is the effect of less friction on an object's speed?

Back

Less friction can increase the speed of an object.

Front

Can friction be beneficial? Give an example.

Back

Yes, friction is beneficial for walking, as it prevents slipping.

Front

What happens to friction when a surface is lubricated?

Back

Lubrication reduces friction between surfaces.

Front

What is static friction?

Back

Static friction is the friction that prevents two surfaces from sliding past each other.
