A farm boy studying physics believes that he can fit a13.0-m-long pole into a 10.0-m-long barn if he runs fastenough, carrying the pole. Can he do it? Explain in detail.How does this fit with the idea that when he is running thebarn looks even shorter than 10.0 m?

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
