an example of _____
velocity
speed

Explanation:

Speed is a scalar quantity that measures how quickly an object is moving and has no direction associated with it. In the given statement, "The ball moved at 7mph as it fell through the hoop", only the magnitude (7mph) is mentioned without any direction. Velocity, on the other hand, is a vector quantity which includes both magnitude and direction. Since the example only provides the magnitude of the ball's movement, it fits the definition of speed.

Answer:

Speed
