When observing a hummingbird at 3.0 s, how is its motion characterized?

In this scenario, the motion of a hummingbird at 3.0 seconds can be interpreted based on its typical behaviors. Hummingbirds are known for their ability to quickly change directions while flying, which is often observed as they navigate around flowers or other objects in their environment.

When considering the correct choice of speeding up and turning, it reflects the dynamic nature of a hummingbird's flight. Typically, these birds can accelerate rapidly to catch prey or avoid obstacles while simultaneously changing their path. Acceleration implies a change in velocity, which includes both changes in speed and changes in direction.

In contrast to constant speed or slowing down, the combination of speeding up and turning captures the active and agile movements that characterize a hummingbird’s flight as it often involves both increasing speed—especially when darting to a new position—and changing direction. Thus, recognizing the nuances of aviary dynamics reveals why speeding up and turning is more indicative of a hummingbird's behavior in motion at the given time.
