Question

While an object near the Earth's surface is in free fall, what changes occur in its mass, velocity, and acceleration?

Answer 1

An object in free fall near the Earth's surface does not change in mass, but its velocity increases as it falls. The acceleration of the object remains constant at an average value of 9.8 m/s².

Step-by-step explanation:

While an object is in free fall near the Earth's surface, its mass remains unchanged. This is because mass is a measure of the amount of matter in an object, and it does not change with the object's motion. The object's velocity, however, increases as it falls. This is because acceleration due to gravity causes the object to continuously gain speed. Finally, the object's acceleration remains constant during free fall near the Earth's surface, with an average value of 9.8 m/s².
