What is the meaning of freefall?
Expert Solution & Answer
To determine
To explain: The meaning of a free fall.
Explanation of Solution
Introduction:
When an object falls, it is accelerated downward due to gravitational force exerted by theEarth.
Earth attracts every object towards itself with a gravitational force. In free fall,there will be no air resistance and force acting on an object except gravity. During free fall, the acceleration of an object is constant and equal to
Conclusion:
Therefore, free falling objects are those objects which falls under gravity.
