How fast do you have to be going before you would be said to have a relativistic velocity?
selfAdjoint said:The dilations happen at all speeds, even 3 mph. The question is when does the size of the dilations become of interest to you?
Yep. So even saying .1C is incomplete: it depends on the situation.whydoyouwanttoknow said:So your average GPS sat. is going at a relativistic speed because if you didn't take time dilation into account they'd give you the wrong position? But for the rest of us who cares that our car is going 60kph?
A relativistic velocity is a velocity that is close to the speed of light, which is approximately 299,792,458 meters per second. This is also known as "relativistic speed" or "relativistic motion."
Relativistic velocity takes into account the principles of special relativity, which states that the laws of physics are the same for all observers in uniform motion. This means that as an object approaches the speed of light, its mass increases and time slows down, making it impossible to reach the speed of light.
A relativistic velocity can vary, but it is generally considered to be any velocity that is at least 10% of the speed of light (approximately 29,979,245.8 meters per second).
Objects with relativistic velocities include particles in accelerators, such as the Large Hadron Collider, and cosmic objects like stars and galaxies. In everyday life, we do not encounter objects with relativistic velocities.
According to the principles of special relativity, it is impossible for anything with mass to travel at the speed of light. However, massless particles, such as photons, do travel at the speed of light.
