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 happens to the temperature of a surface when friction is created?

Back

The temperature of the surface increases due to the heat generated by friction.

Front

What is an example of friction in everyday life?

Back

Rubbing your hands together to keep warm is an example of friction.

Front

What can increase friction between two surfaces?

Back

Adding weight or using rough surfaces can increase friction.

Front

What is the effect of friction on moving objects?

Back

Friction slows down moving objects and can eventually stop them.

Front

How does friction help us in daily activities?

Back

Friction helps us walk without slipping and allows us to hold objects securely.

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 opposes the motion of an object that is already moving.

Front

What happens when you slide a book across a table?

Back

Friction between the book and the table slows the book down.

Front

How can you reduce friction?

Back

You can reduce friction by using lubricants like oil or by smoothing surfaces.
