Question

a parachute helps a person land safely how

Answer 1

If you notice, you will see that parachute is like a half cut balloon. Also, a parachute is very light weight but large. The large area traps lot of air in it during the fall. Now, you know that everything falls down because of gravity. What happens here is that this trapped air creates a push upwards that works against the gravity. This slows down the parachute and whatever is tied to it.
It is similar to a situation where you are putting a lot of force to run fast in the forward direction and somebody comes and starts pulling your hand backwards. You wouldn’t be able to run that fast. Right? Parachute is designed to create a force that lessens the pull of gravity. So the person wearing a parachute falls down slowly and safely to the ground.
Now a little bit of history. Artist Leonardo da Vinci drew first ever sophisticated design of a parachute. He drew a cloth-covered wooden frame in the shape of a pyramid and it had a man hanging underneath. Many years later a Frenchman Louis-Sébastien Lenormand implemented modern parachutes. In 1783, he made the first successful jump.
