How does the acceleration due to gravity affect the velocity of a falling object?
The acceleration due to gravity increases the velocity of a falling object, causing it to fall faster over time.
The velocity of a falling object remains constant regardless of gravity.
The acceleration due to gravity decreases the velocity of a falling object.
Gravity has no effect on the velocity of a falling object.

What is the difference between instantaneous speed and average speed in freefall?
Instantaneous speed is the speed at a specific moment; average speed is total distance divided by total time.
Average speed is the speed at a specific moment; instantaneous speed is total distance divided by total time.
Instantaneous speed is calculated by averaging speeds over time.
Instantaneous speed is always greater than average speed.
