Yogita Ingle 7 years, 10 months ago

Metalloids exhibit some properties of metals as well as of non-metals. Hence, they are also known as semi-metals. Boron, silicon, germanium, arsenic, antimony, and tellurium are the most commonly recognised metalloids. These elements run diagonally across the Periodic Table. They may have metallic or dull appearance. They are usually brittle and are fair conductors of electricity. They may gain or lose electrons during chemical reactions. They form alloys with metals. They are used as catalysts, biological agents, flame retardants, alloys and semiconductors in industries due to their unique properties.

Rolling friction come into play when we try to roll one body on another body

0Thank You

Yogita Ingle 7 years, 10 months ago

For a moving solid body, there are two principal types of friction that act upon it:

The force resisting the motion of a rolling body on a surface is known as Rolling friction or Rolling resistance. This type of friction is experienced by a wheel or a ball rolling on the ground.
There is another type of friction known as Sliding friction, which resists the movement of a body which is pushed in such a way that only one surface of the body is in contact with the surface it is moving on. It will be experienced when, for example, a box is pushed across a table.

Rolling friction is considerably weaker than Sliding friction.
