Difference between running into a bullet and being shot

6 posts in this topic

The catridge of a pistol is lethal because of its speed of 700-900 m/s. If I would move of at a speed of 700-900 m/s and would move into a catridge that is just hanging on a band facing in my direction would there be a difference between that and being shot?

You would take a lethal shot, but your skin would fly off your face before that :)

700 to 900 m/s ist 2520 to 3240 km/h. 
A military jet can fly 1930 km/h.

Now everything makes sense.

Imagine Flash trying to stop a bullet that flies with 3000 km/h with a finger while running 2990 .. 2980 .. 2970 .. 20 .. 10 km/h. If he would stop abruptly his finger would get blasted.

Some fun insight on relativity: when you're in free fall above Earth (granted a vacuum), your movement can be described as an acceleration (~9.81 m/s^2). But when you're in free fall, it doesn't feel like you're accelerating in the same way as if you were driving a car and pushing in the gas pedal (no feeling of inertia). So why does writing it as an acceleration work as a model for describing the movement induced by gravity? Well, you have to think about it as not you being accelerated towards the Earth, but as the Earth being accelerated towards you :D 

I guess the proper way to describe it is that when on Earth, gravity is a constant force acting on your body, and that attaining the acceleration associated with free fall just requires removing whatever force is keeping your body at rest (e.g. your feet on the ground). Simply removing a force that is acting on you doesn't lead to inertia. It's only when a new force starts acting on you that there is inertia. So we're really always falling, but we've just gotten used to keep ourselves up :D
