Describe any three ways in which friction between surfaces can be reduced.

Explanation

**Step-by-Step Solution:**

1. **Making Surfaces Smooth by Polishing:**
- One effective way to reduce friction is to make the surfaces that are in contact as smooth as possible. This can be achieved through polishing. When surfaces are polished, the microscopic irregularities that cause friction are minimized, leading to smoother interactions between the surfaces.

2. **Using Lubricants:**
- Another method to reduce friction is by applying lubricants such as oils, greases, or other substances. Lubricants fill in the gaps and irregularities between the surfaces, creating a thin film that allows them to slide over each other more easily. This significantly reduces the frictional force.
