Define sig figs and name the 5 rules
Indicates accuracy of the measurement.
- All non zeros are sig
- All zeros between non zeros are sig
- Zeros on the end of a decimal are sig

Density is equal to…
Mass (or weight) divided by volume
Define force and give the formula
Created by acceleration; F=ma
Give formula if weight is a force
Fw=mass X acceleration of gravity
