Solution

1. Highly polished Surfaces.
Reason: There will be friction between in other two cases. In highly polished surfaces, there will not be any friction.

2. Sand
Reason: Oil, Greese, Graphite Powder are the substances to reduce friction.

3. Cart
Reason: Others are in streamlined shape

Q. Two highly polished metal surfaces have negligible friction between them.

Q. If two surfaces are polished highly smooth, the friction between them increases.

Consider the following statements:

Statement 1: Rough surfaces generally have more friction between them.
Statement 2: When we attempt to slide one surface over another, we have to apply a force to overcome interlocking between the irregularities present on the surfaces.

Choose the correct option.

Q. The causes of friction are molecular adhesion, interlocking of surface irregularities and plowing effect.

Consider the following statements:

Statement 1: Irregularities on two surfaces lock into one another.

Statement 2: We have to apply a force to overcome the interlocking so as to move any of the two surfaces in contact.
