​

Answer 1

Answer:

Shown from explanation

Explanation:

You have heard that expression what ever goes up must come down that's usually used to mean when you throw an object up, it comes down on its accord. This is due to a force on the earth that occurs in nature known as gravity.

So when an object falls under this influence it's said to fall freely.

Note not all heavenly bodies have gravitational pull, from experience by scientists who went to the moon they found out whatever goes up keeps flying endlessly so in that case an external force is needed to keep objects in the moon on ground level.

Hence the parachute falls on earth freely without an external force but on the moon it must fall with an external force inputed on the parachute system.

This means in the earth we have free fall but in the moon no such thing exist. So a body falls freely when there is gravity.
