Give me the Proton
Exploring how this affects our
measurement of length.
With a mass of 3.2 x 10-27 kg the proton
will accelerate at:
This means, that in one second, the earth will see the
proton accelerate to:
Hey! Newton's 2nd Law and kinematics gives the same
velocity as that observed!
This means that the earth's frame would see the proton
d=( 256,000,000 m/s)(1 s)
d = 256,000,000 m
Bringing it back together:
We push a tiny proton and expect to see it travel
270,000,000 m in the 1.0 second after our push. Instead
we see it travel at 0.85 c, which makes it travel
This is much less than the 270,000,000 meters we
expected. It is less by 14,000,000 meters or 8700
- The proton isn't acting as we predict. It is
acting (more massive, less massive, as massive) as a
proton at rest.
