# Physics equations question watch

1. I don't know how to start with this question:
Demonstrate that the following equation is homogeneous with respect to units. The symbols have their usual meanings.
x = u t + 1/2(a t^2)
2. x is measured in meters
u is measured in meters per second
t is measured in seconds
a is measured in meters per second squared
1/2 is dimensionless (no units)

Run through the units and make sure that you have the same thing on both sides when you multiply through.
