Question

section 5.2

1. give a reasonable explanation for why the friction is so low between an ice skate blade and the ice.

Explanation:

When an ice skate blade is in contact with ice, the pressure exerted by the blade causes a thin layer of ice to melt. This thin layer of water acts as a lubricant, reducing the friction between the blade and the ice.

Answer:

The pressure from the ice skate blade causes a thin layer of ice to melt, and this water layer lubricates, reducing friction.
