Answer» Answer: A free-falling object has an ACCELERATION of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most ACCURATELY known as 9.8 m/s/s. There are slight variations in this numerical value (to the SECOND decimal place) that are DEPENDENT primarily UPON on altitude. |
