FRICTION

Front

What is friction?

Back

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

Front

Does friction act in the same direction as the motion of an object?

Back

No, friction acts in the opposite direction to the motion of the object.

Front

What type of surface produces greater friction?

Back

Rough surfaces produce greater friction compared to smooth or shiny surfaces.

Front

What is static friction?

Back

Static friction is the force that prevents an object from starting to move when a force is applied.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of an object sliding over a surface.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object that is rolling over a surface.

Front

What is an example of rolling friction?

Back

An example of rolling friction is when a skateboard rolls on the ground.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk without slipping, helps vehicles to stop, and enables objects to stay in place.

Front

How can friction be reduced?

Back

Friction can be reduced by using lubricants, smoothing surfaces, or using wheels.

Front

What happens to friction when the surface area increases?

Back

Increasing the surface area does not significantly affect friction; it mainly depends on the nature of the surfaces in contact.
