An object that is falling freely has a constant what?
|
|
speed
|
|
|
velocity
|
|
|
acceleration
|
|
|
nothing is constant
|
Explanation:
Detailed explanation-1: -Freely falling bodies near the earth’s surface gain constant acceleration called the acceleration due to gravity. For earth, the acceleration due to gravity near its surface is 9.8 m/s2.
Detailed explanation-2: -With algebra we can solve for the acceleration of a free falling object. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth. The weight, size, and shape of the object are not a factor in describing a free fall.
Detailed explanation-3: -Acceleration due to gravity acting on a body having free fall is zero.
