Wednesday Planner: Test Friday Today: Measuring MASS and WEIGHT
Set up for Cornell Notes on the back of your Metric Mania sheet from Tuesday • Topic: Mass and Weight • Essential Question: Why are mass and weight not the same?
Measuring • Mass is the amount of matter in an object • Triple-beam balance • Grams/Kilograms • Weight is how hard gravity is pulling on an object • Spring scale • Newtons
Gravity • All objects exert gravity • Gravity is a weak force • Planets with greater mass exert more gravity (pull harder on objects) • Gravity pulls toward the center of a planet • Weight is a measure of how hard gravity is pulling on an object.
To do… • Use your planetary chart to write the planets in order from most gravity to least gravity. How do you know? • Measuring Mass and Weight Lab Sheet • Keys, Pencil pouch, Dish soap, Science or Math journal, Planner or…
