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.

Why do we not observe relativistic effects in our daily lives? O Because motion is relative. O Because you can't go back in time. Because the math is too hard. O We do observe relativistic effects in our daily lives. This is why time sometimes appears to pass more quickly than usual. O Because relativity only effects particles such as electrons & protons. O Because the speeds we move at are much less than the speed of light.
