In physics, friction is said to be the opposing force that resists any object. Testing which surface is more effortless to slide a block across can be used to investigate friction. Thus, option c is correct.

What is friction?

Friction has been defined as the resisting force that opposes the movement of objects across the surface. It can also be said as a force that opposes the relative motion of an object.

The friction can be rolling, sliding, fluid, or static depending on the surface and type of object. The frictional force is present only when the object has been in contact of the surface body.

When a surface is tested for sliding the wooden block, then the sliding friction has been used. It is possible as the resistant force of the surface with respect to the block is taken into the consideration.

Therefore, option C. the surface testing for sliding wooden blocks involves friction.
