Answer:
The experimental term is called free fall
Step-by-step explanation:
The free fall is called movement due solely to the influence of gravity.
All bodies with this type of movement have a downward acceleration whose value depends on where they are. On Earth this value is approximately 9.8 m / s2, that is to say that bodies left in free fall increase their speed (down) by 9.8 m / s every second.
In the free fall the air resistance is not taken into account.
