It is difficult to walk on an icy road, because your feet keep slipping on the ice.
The high heels sink into the sand.
Sand has a very low bearing capacity. Hence, your feet tend to sink into it.While walking, you have to continually 'dig' yourself out of the sand with every step you take.
To understand what it is difficult to walk on sand we need to know how do we walk? Walking is a process where we put pressure on earth and when one of our legs is pressing the earth hard we take our other leg in air and take a step. This process is ok with hard earth but if we are on sand, our leg started going down inside sand and that is why we feel hard to walk on sand.
yes
Because the pointy rocks stap your feet
It is hard to walk on sand as - first we need to understand how we walk. every action has an equal opposite reaction (i.e. when we walk on earth we put a certain amount of force on the ground that reverts that force back on us) but when we walk on sand it is not hard and soft we fall into it and it doesn't give us and EQUAL opposite reaction.
no
When you walk on sand two thing happen that makes it hard to walk 1. the ground is uneven making you feet shift and slip 2. sand gets on you foot causing resistance. hope this helps!

It is difficult to walk on a slippery road because the friction between your shoes and the road is compromised. When you stand, its not so much an issue, as most or all of the force vector from your body is pointing down. When you walk, however, there is a horizontal component of the force vector, which is what is accelerating you in a horizontal direction. Since the road is slippery, the coefficient of friction between your shoes and the road is less, causing the tendency to slip or fall.
Well you do make sense..............well this because when you are to walk on a smooth road ,you fall.That's because the friction is less beetween your foot and road and thus there is no grip.
