Notes

Essential Question(s)What is mass? What is weight? How are they differentfrom each other? How do I measure these properties?What are metric units of measure for mass and weight?

Tennessee SPI Objective:Distinguish between mass and weight using

appropriate measuring instruments and units.

Check for UnderstandingExplain the difference between mass and weight.

MassKey Questions

Mass is the amount of matter in an object. In other words it is how much "stuff" is in an object. Everything that is made of matter has mass. Anything that is solid, liquid, gas, or plasma has mass.

Mass: What is it?

We measure mass with a triple-beam balance or an electric balance (there are various kinds)

Unit of measure for mass: Examples: milligrams (mg), grams (g), kilograms (kg)

Mass: How is it measured?

We are measuring the amount of matter in the object Exact same measurement on the Earth & the Moon

Triple-Beam BalanceElectric Balance

Grams

Mass does not change from planet to planet (weight does)Example:-A full/unopened can of coke on Earth has a mass of 390g.-The same unopened can on Mars would have the same mass (390g)

WeightKey Questions

Weight is the measure of gravity’s pull on an object. In other words it is how “heavy" an object feels. Everything that is made of matter has weight. All solids, liquids, gases, and plasma have weight.

Weight: What is it?

Measure weight by using a scale (there are various kinds) We are actually measuring the force of gravity's pull

SPI 0807.12.4Mass and WeightNotes Science

Unit of measure for weight:

Weight: How is it measured?

Different measurements on the Earth & the Moon

Newtons (not pounds!)

Earth Mars

Weight changes from planet to planet, but mass does notExample: A full/unopened can of coke on Earth weighs 3.61 Newtons. The same unopened can on Mars would weigh 1.20 NewtonsWhy? Mar has less mass than Earth & therefore has less gravity
