FAQs on Problems on Relativistic Velocity- 3 Video Lecture - Crash Course for IIT JAM Physics

1. What is relativistic velocity?
Ans. Relativistic velocity refers to the velocity of an object as observed from a reference frame that is moving relative to the object. It takes into account the effects of special relativity, which states that the speed of light is constant and that time and space can be distorted at high speeds.
2. How is relativistic velocity different from classical velocity?
Ans. Relativistic velocity differs from classical velocity because it incorporates the principles of special relativity. In classical physics, velocities add linearly, but in relativistic physics, velocities add using the relativistic velocity addition formula, which takes into account the effects of time dilation and length contraction at high speeds.
3. Can an object have a velocity greater than the speed of light?
Ans. According to the principles of special relativity, it is not possible for an object with mass to have a velocity greater than the speed of light in a vacuum. As an object with mass approaches the speed of light, its relativistic mass increases, making it more difficult to accelerate further.
4. How does relativistic velocity affect time dilation?
Ans. Relativistic velocity affects time dilation by causing time to dilate or slow down for objects that are moving relative to an observer. As an object's velocity increases, time dilation becomes more significant, meaning that time appears to pass slower for the moving object compared to a stationary observer.
5. What are some practical applications of relativistic velocity?
Ans. Relativistic velocity has practical applications in various fields such as particle physics, astrophysics, and GPS technology. For example, particle accelerators rely on relativistic velocity to accelerate particles to high speeds for experimental purposes. In GPS technology, relativistic effects must be taken into account to ensure accurate positioning calculations due to the high velocities of GPS satellites.
