Question

Why why is it difficult to pull a boat on beach then on sea

Answer 1

It is difficult to pullthe boat on the beach because of the friction between the boat and sand. But in the sea, there is less friction between the sea water and the boat. Hence, it is easier to pull the boat in the sea.

Answer 2

Answer:

When a boat is on the sea, its surface is in contact with water while when it is on the beach, its surface is in contact with beach sand. There is more friction between the boat and the beach surface than between the boat and the water. As a result, it is more difficult to pull a boat on the beach than on the sea.
