4 MASS WEIGHT HOW IS MASS DIFFERENT FROM WEIGHT? Mass is a measurement of how much matter is in an object or substance.Weight is a measurement of how strongly GRAVITY is PULLING an object DOWN.Weight changes when gravity changes…so on the moon where there is less gravity, you will weigh less, but on the sun you would weigh more!Mass does NOT change if you travel to another planet.ON EARTHMass: 64.5 kgWeight: 140 lbsON MOONMass: 64.5 kgWeight: 23 lbsON SUNMass: 64.5 kgWeight: 3,914 lbs
5 FINDING THE MASS OF OBJECTS USING A TRIPLE-BEAM BALANCE
6 To find the MASS (the amount of matter) in an object, you can use a tool called a TRIPLE-BEAM BALANCETRIPLE-BEAM BALANCEPanRidersBeamsPointer(at zero)
7 READING THE MASS ON A TRIPLE-BEAM BALANCE 1) Read the number on the HUNDREDS BEAM30 gramsAdd the number onthe TENS BEAM100 gramsAdd the number on theONES BEAM*Any marks past thenumber on the onesbeam are to be readas TENTHS using aDECIMAL POINT first.7.4 gramsThe object measured on thisbalance has a mass of:= grams
8 What is the mass of the object on this triple-beam balance? =373.3 grams70 g300 g3.3 g
12 Let’s practice reading the measurements on some balances.
13 Let’s find the mass of some objects at your desk! Make sure the pointer on your balance is setat ZERO.Place an object on the pan.Follow the STEP-BY-STEP directions in yournotes for READING A TRIPLE-BEAM BALANCE
