A person can land safely from a significant height with the help of parachute .Give reason.
Answers
Explanation:
because cold air is is heavy that's why parachute go up and hot air is weightless that's why parachute goes down
Answer:
A parachute landing fall (PLF) is a safety technique that allows a parachutist to land safely and without injury. The technique is performed by paratroopers and recreational parachutists alike. The technique is used to displace the energy of the body contacting the earth at high speeds.

Introduction
Have you ever wondered how a parachute works—or which design features are most important in slowing someone's descent? Parachutes come in many different shapes and sizes, but they work based on the same general principles. In this activity, you will test differently sized parachutes to see how changes in the size of the parachute affect flight. What do you think will work better: a bigger parachute or a smaller one?
Background
In the sport of skydiving, a person jumps out of an airplane from a very high altitude, falls through the air, and releases a parachute to help the skydiver slow his or her way down and land safely on the ground. How does the parachute break the free fall so well?
As the skydiver is falling, the force of gravity is pulling the person and his or her parachute toward the earth. The force of gravity can make an object fall very fast! The parachute slows the skydiver down because it causes air resistance, or drag force. The air pushes the parachute back up and creates a force opposite to the force of gravity. As the skydiver falls, these "push and pull" forces are nearly in balance.*
