1.
The Lorentz factor for v = 0 is
1
∞
c
0
2.
Which equation is correct for t′?
t
γ(t + vx)
γ(t − vx/c2)
γ(t − vx)
3.
For v = 0.60c, γ equals
0.80
1.25
1.67
2.00
4.
At low speeds the Lorentz transformations reduce to
x′ = x, t′ = t
x′ = γx
x′ = x + vt
x′ = x − vt, t′ = t
5.
Two events are simultaneous in S and at different x. In S′ they are
always simultaneous
not simultaneous
at the same place
impossible
6.
Which coordinate is unchanged for motion along x?
x
t
y
none
