Question

*Free fall is only possible ______.*

1️⃣ in air
2️⃣ everywhere
3️⃣ in a vacuum
4️⃣ at the poles​

Answer 1

3️⃣ in a vacuum

Explanation:

Free fall is possible only in vacuum. This is said that free fall is given only by the attraction force by earth gravity. Hence, if Air will be there then the free fall is not possible.

Answer 2

Answer:

Free fall is only possible in a vacuum.

Explanation:

This is because in vacuum, the force of viscosity is not offered by the air (or any other fluid). This makes your acceleration during fall exactly equal to 'g', i.e.; . Thus, you may consider it to be a true free fall....
