Free Fall Acceleration
All free-falling objects on Earth accelerate downwards at a rate of 98 mss often approximated as 10 mss for back-of-the-envelope calculations Because free-falling objects are accelerating downwards at a rate of 98 mss a ticker tape trace or dot diagram of its motion would depict an acceleration. Lets say that down is negative.

What is the magnitude of the free-fall acceleration at the orbit of the Moon a distance of 60RE from the center of the Earth with the radius of RE.
Free fall acceleration. As we said earlier gravity varies depending on location and altitude on Earth or any other planet but the average acceleration due to gravity on Earth is 98 m s2 m s 2. Freefall as its term says is a body falling freely because of the gravitational pull of the earth. If something falls freely under the effect of earths gravity without any effect of air then the phenomenon is called free fall.
17 rows acceleration does not change while the object is in free fall. The weight size and shape of the object are not a factor in describing a free fall. This motion will have the effect of acceleration due to gravity.

You can see a lis. Freefall refers to a situation in physics where the only force acting on an object is gravity and hence acceleration due to gravity. The acceleration experienced by an object falling freely in a gravitational field also known as the acceleration due to gravity.
No other force including air resistance is acting on such an object. If you throw something vertically upward and could somehow eliminate or ignore the effect of drag and air on the object Then the object accelerates constantly when it goes up and falls down This is called free fall.
