Question

A person can run fast on a hard ground, but cannot swim that fast in water. State your reasons in not more than 50 words.

pls give me correct answer i will mark ur answer as brainliest !!!

Answer 1

The reasons which are responsible for a person which makes him/her runs faster than in comparison to swimming in water are as follows :-

➊ The First and the most known reason is ❝Friction❞

Friction is responsible for this as we all know there is a frictional force somewhere, and in different form somewhere more & somewhere less

So, on land when we run the ground applies frictional force, but in water the water has more friction cause there are many things inside like salts and other minerals mixed which makes the density higher and somehow there more friction is produced.

➋ The Second reason is Pressure

We know on the land pressure depends on two things force applied and the area (P = F/A) .

But, inside water pressure depends on density, acceleration due to gravity & height ( P = ρ g h)

So, inside water more pressure is applied and somehow reduces the speed of swimmer

So, these two were the main reasons
