Final answer:
The velocity of a falling object ignoring air resistance is determined by the constant acceleration of gravity, which is about 9.80 m/s² on Earth, resulting in an increase in velocity until terminal velocity is achieved.
The correct option is c.
Step-by-step explanation:
Ignoring air resistance, the velocity of a falling object increases due to the constant acceleration caused by gravity. On Earth, this acceleration due to gravity is approximately 9.80 m/s², which applies to objects regardless of their mass.
However, if we consider air resistance, an object will eventually reach a terminal velocity, which is a constant velocity achieved when the force of gravity is balanced by the drag force, and the object no longer accelerates.
It's important to note that regardless of the path of the object (whether it's moving upwards initially or downwards), the acceleration due to gravity remains constant throughout the movement.
This acceleration is constant until objects reach terminal velocity in a fluid medium, at which point they will continue to fall at this constant speed.
The correct option is c.
