Relativistic Addition of Two Speeds
v = (u + w)/(1 + u·w/c^2)
What it says
Speeds do not simply add; this keeps the result below c however fast the parts are.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
v | Combined speed (m/s) | L T^-1 |
u | First speed (m/s) | L T^-1 |
w | Second speed (m/s) | L T^-1 |
Work it out
Enter what you know. No account needed.
Fill in all but one: u, w, v are all empty.
