How do I calculate velocity of an object if I know its Lorentz factor?

[Gurh]

The question I have for my physics homework is "What does the velocity of an object need to be if it's Lorentz factor is 2?"
I know the equation for the Lorentz factor is γ = 1/sq(1-(v^2/c^2)) I just don't know how to get the velocity out of it.
I'm a bit of a math and physics noob so that might bit a slight problem aswell! :P Any help is appreciated!

You need to rearrange the equation, you know γ is 2 and c is the speed of light which is constant so you can find v which is the velocity of the object.

It is pretty simple algebra, have you attempted to try? Possibly show some work and we can be of more help.

To calculate the velocity of an object given its Lorentz factor, you can rearrange the equation γ = 1/√(1-(v^2/c^2)) to solve for v. This can be done by multiplying both sides by √(1-(v^2/c^2)) and then taking the reciprocal of both sides.

The resulting equation is v = c√(1-(1/γ)^2). Therefore, to find the velocity of an object with a Lorentz factor of 2, you would substitute 2 for γ in the equation and solve for v. This would give you a velocity of approximately 0.866c, where c is the speed of light.

It is important to note that the Lorentz factor is a measure of how much an object's time and length measurements change when it is moving at a significant fraction of the speed of light. So, a Lorentz factor of 2 means that the object is moving at approximately 86.6% of the speed of light.

I hope this helps with your homework and understanding of the Lorentz factor and velocity in special relativity. Keep in mind that it is always important to double check your calculations and units to ensure accuracy. Good luck with your studies!
