Will a Bullet Shot Straight Up Fall Back to Its Starting Point?

In summary, the conversation discusses the trajectory of a bullet shot straight up into the air from the surface of the Earth. It is established that the bullet is shot from a stationary position on the Earth's surface and is not moving faster than 6km/s. The conversation also explores factors such as the Earth's rotation and conservation of momentum. Ultimately, it is determined that the bullet would not fall back to the same spot due to the Earth's rotation and the acceleration of the reference frame.

If we shoot bullet to the air (90Degree) it will fall down to same spot or not ? (Without anther force)
Thanks

Well, where are you shooting from?

I assume that the bullet is not going more than 6km/s?
 
  • #3
From the ground (yes not over 6km/s). Could you give me answer and explanation ?
Thanks
 
  • #4
6km/s is Earth escape velocity. I think you'll find that the problem specifies that the bullet is being shot from the surface of the Earth.

If you shot the bullet straight up out of a moving car, would it come down and hit you? What if the car was turning? What if the someone stomped on the brakes?

Yes the bullet shot from the surface of the Earth and pistol is not moving. So it should fall down in the same spot ,right ?
 
  • #6
We did not talk about another factor. (No other facetor in this situation)
 
  • #7
Is the Earth stationary?
 
  • #8
earth is still moving around itself
 
  • #9
So, would the bullet move with the Earth after you shot it?
 
  • #10
Yes. Conservation of momentum.
 
  • #11
Could you explain about conservation of momentum ? Thanks

Actually, since the Earth is spinning, the reference frame is accelerated, so the bullet would not be moving with the earth.
 
1.

What is the trajectory of a bullet fired into the air?

The trajectory of a bullet fired into the air follows a parabolic path, meaning that it will travel up and then back down in a curved shape.

2.

How far can a bullet travel when fired into the air?

The distance a bullet can travel when fired into the air depends on a variety of factors, including the type of gun, the angle at which it is fired, and air resistance. In general, a bullet can travel up to a few miles when fired at a high enough angle.

3.

What happens to a bullet when it reaches its highest point in the air?

At its highest point, the bullet has reached its maximum height and begins to fall back down due to the force of gravity. As it falls, it will pick up speed and eventually reach the ground.

4.

Can a bullet fired into the air kill someone when it falls back down?

Yes, a bullet fired into the air can still be deadly when it falls back down. The force of gravity and air resistance can slow it down, but it can still have enough velocity to cause serious injury or death.

5.

Is it illegal to fire a bullet into the air?

In most places, it is illegal to fire a bullet into the air. This is because it can be dangerous and can potentially harm people or property when it falls back down. It is important to always follow proper gun safety protocols and laws when handling firearms.
