A freely falling body has a constant acceleration of 9.8 m/s².This means that: A)the body falls 9.8 m during each second B)the body falls 9.8 m during the first second C)the speed of the body increases by 9.8 m/s during each second D)the acceleration of the body increases by 9.8 m/s² during each second E)the acceleration of the body decreases by 9.8 m/s² during each second

Question

Quizplus · Accepted Answer

The constant acceleration of 9.8 m/s^2 means that the speed of the body increases by 9.8 m/s during each second of free fall. Option A is incorrect because the distance falls each second increases as time passes. Option B is incorrect because the body continues to fall with the same acceleration after the first second. Options D and E are incorrect because the acceleration itself is constant throughout the free fall.
