objects in free fall near the surface of earth experience
a. constant speed
b. constant velocity
c. constant acceleration
d. constant distance
Only if you consider air resistance, and the object has reached terminal velocity does it have constant speed.
Relook at answer c.
speed
The correct answer is c. constant acceleration.
When objects are in free fall near the surface of the Earth, they experience a constant acceleration due to gravity. This means that the object's velocity is constantly increasing in the downward direction.
To understand why this is the case, we need to consider the force acting on the falling object. In this case, the force of gravity is the only force acting on the object, causing it to accelerate towards the Earth. The acceleration due to gravity near the surface of the Earth is approximately 9.8 meters per second squared, denoted as "g".
So, during free fall, the object's velocity is constantly increasing by 9.8 meters per second every second. This implies that the object's acceleration is constant. It is important to note that this constant acceleration only occurs in the absence of air resistance. If air resistance is present, it could affect the object's motion and the acceleration might not be constant.
i think a
As bobpursley pointed out implicitly this question is worded poorly. Ignoring air resistance it falls at about 9.81 m/s^2 acceleration downward, the acceleration of gravity. However after a high speed is reached air resistance does become important depending on the shape and it converges to constant velocity when the drag becomes equal to the weight, mg.
Sorry about being long winded but this is important.
