# Lift Weight

Pam normally weighs $\SI{60}{\kilo\gram},$ but one day she measured her weight in an elevator as $\SI{70}{\kilo\gram}.$

Can we say for sure whether the elevator was moving up or down at the moment she measured her weight?

The red arrows indicate the direction of motion.

Hint: Consider not just the velocity, but the acceleration of the elevator. Do velocity and acceleration always have the same direction?
