Answer 2

The analogy is completed below:

1. Knot in a thread : friction :: Ball bearing: friction

2. Downward force : Weight :: Upward force offered by liquid : Buoyant force

• A knot in a thread causes friction. Similarly, ball bearing reduces friction. The downward force is the weight caused by gravity. Similarly, upward force by liquid is the buoyant force.
• When a body is immersed in a liquid, it displaces an amount of liquid. The body experiences an upward force equivalent to the mass of the liquid displaced.
• This upward force is called buoyant force, which is responsible for the floating of objects.
• Objects having density more than liquid will sink in it while objects with density lesser than the liquid will float in it.
