Briefly explain in words why relativity states that more force is required to accelerate a particle from 0.4c to 0.8c than from 0 to 0.4c. Why this contradicts the Newtonian physics ?
Homework Answers
In relativity moving mass increases as compared to rest mass hence when speed closes to speed of light force required to accelerate with same acceleration also increases as mass increases. Where as in Newtonian physics mass is always constant. It doesn't depend on increasing velocity. Hence force is also constant for same acceleration.

4. Experiment has shown the Strong nuclear force to be many orders of magnitude greater than the Coulomlb force at very small distances, but drops off more quickly and becomes negligible at distances larger than the nucleus of an atom. One possible function that obeys this behavior is given by a force that drops off as 1/r Imagine that you model the strong nuclear force as: Ba1a2 F. st where B is the proportionality constant (or the 'coupling constant) which...
