if a humming bird is hovering in a car going at a constant rate, and the car comes to a sudden stop, will the bird fly into the windsheild?

Do *YOU* fly toward the windshield when the car suddenly stops? (hint: why are you wearning a seatbelt?) There's your answer.Originally posted by socialcoma

The hummingbird isn't floating - its FLYING. Huge difference.when it is floating, it is staying in place in the "bubble" of air in the car...when the car brakes, in order for the hummingbird to hit the windshield, all that air would have to be smashed forward...which would leave a vacuum in the back and then that would be filled up...so wouldn't it get really windy in the car whenever u stop?

Buoyancy depends on the density of an object, not its mass. As the humming bird has a higher density than air but the helium balloon a lower density, they will not behave identically, i.e. the humming bird will fly against the windshield if you brake the car (unless it can react very quickly and brake as well).Originally posted by LURCH
I think not. Like the hellium balloon, the humming bird rides the air within the vehicle. Admittedly, the humming bird is less bouyant than the balloon, but it is also far less massive than a person
Inertia is the tendency of an object to resist changes in its state of motion. This means that an object in motion will continue moving at a constant velocity unless acted upon by an external force. In the case of a hummingbird hovering in a car, the bird is able to maintain its position and speed relative to the car due to its inertia.
The hummingbird's small size and light weight allow it to have a high power-to-weight ratio, meaning it can generate enough lift from its wings to counteract the force of the car's motion. Additionally, the bird's wings are able to make rapid adjustments to maintain its position using the surrounding air as a reference point.
The hummingbird's ability to hover in a car is affected by its size, weight, wing shape and size, and the speed and direction of the car. Other factors such as wind speed and air density can also play a role in the bird's ability to maintain its position.
Yes, there is a limit to how fast a hummingbird can hover in a car. As the car's speed increases, the air resistance and turbulence also increase, making it more difficult for the bird to maintain its position. At a certain point, the bird will not be able to generate enough lift to counteract the force of the car's motion and will be pushed backwards.
When hovering in a car, the hummingbird must also counteract the force of the car's motion in addition to the force of gravity. This requires more energy and effort from the bird compared to hovering in still air. However, the bird's hovering abilities are still impressive regardless of the environment.
