1. For a frictionless object in free-fall (i.e.
no contact forces; falling through the air), what is its approximate
acceleration? Be sure to include units
in your answer.
Thank you for the opportunity to help you with your question!
For such a friction-less free fall, the acceleration will be the acceleration due to gravity.
For Earth, this acceleration due to gravity is denoted by g and its value is 9.8 m /s^2 or 9.8 N/Kg
So, if an object is under free fall towards the surface of Earth, its acceleration will be 9.8 m/s^2
