How does a boomerang behave in empty space and gravity?

In summary, the trajectories of a boomerang and a stone thrown with equal force in a vacuum will be the same due to the lack of aerodynamic forces. However, in an atmosphere, the asymmetrical design of a boomerang allows for asymmetrical lift, causing it to return in a curved path. This is due to the horizontal component of lift, which makes it turn, unlike a stone which would follow a straight trajectory.

If a spaceship throws a boomerang in the vacuum of the space but with some gravity from earth. Will it have the same trayectory than if you throw a stone of equal mass than the boomerang with equal force?
thanks

Yup. There are no areodynamic forces that would make the stone and boomerang's trajectories any different.

As Rolf Harris sang: "My bommerang won't come back".

What makes a boomerang return?

You might post a new thread on this, but it has to do with the wind and their shape.

Asymmetrical design (it's a bit crook one way).

Yes, it is asymmetry that makes them return, but not the asymmetry of their crooked design. Rather, it is asymmetrical lift. Like the rotary wing of a helicopter, when the boomerang is rotating one side (the side going into the wind) generates more lift than the other. This side rises up, causing the entire device to "bank". What aviators refer to as "the horizontal component of lift" then makes it turn. Without an atmosphere, the boomerang would just fly straight along a ballistic trajectory.

1. How does a boomerang behave in empty space?

A boomerang would not behave the same way in empty space as it does on Earth. Without air resistance, the boomerang would continue in a straight line without returning to its starting point.

2. How does a boomerang behave in gravity?

In the presence of gravity, the boomerang will experience a downward force, causing it to curve in its flight path. This is due to the boomerang's shape and the lift it produces as it spins through the air, similar to the way an airplane's wings work.

3. Why does a boomerang return to its starting point?

The unique shape of a boomerang causes it to create lift and spin, which creates a gyroscopic effect. This effect, combined with the boomerang's curved flight path, causes it to return to its starting point.

4. How does air resistance affect a boomerang's flight?

Air resistance can affect a boomerang's flight in several ways. It can slow down the boomerang, causing it to fall to the ground sooner. It can also cause the boomerang to lose lift, making it less likely to return to its starting point.

5. Can a boomerang behave differently in different environments?

Yes, a boomerang's behavior can vary depending on the environment it is thrown in. Factors such as air density, wind speed and direction, and temperature can all impact its flight path and ability to return to its starting point.
